For estimates of the parity-violating α-decay width of ⁶Li*(3.56) [0⁺; T = 1] see (1983RO12, 1984BU01, 1986BU07).

1. (a) ³He(³H, γ)⁶Li Q_m = 15.7955
(b) ³He(³H, n)⁵Li Q_m = 10.13 E_b = 15.7955
(c) ³He(³H, d)⁴He Q_m = 14.32049
(d) ³He(³H, ³H)³He

Capture γ-rays (reaction (a)) to the first three states of ⁶Li [γ₀, γ₁, γ₂] have been observed for E(³He) = 0.5 to 25.8 MeV, while the yields of γ₃ and γ₄ have been measured for E(³He) = 12.6 to 25.8 MeV. The γ₂ excitation function does not show resonance structure. However, the γ₀, γ₁, γ₃ and γ₄ yields do show broad maxima at E(³He) = 5.0 ± 0.4 [γ₀, γ₁], 20.6 ± 0.4 [γ₁], ≈ 21 [γ₃] and 21.8 ± 0.8 [γ₄] MeV. The magnitude of the ground-state-capture cross section is well accounted for by a direct-capture model; that for the γ₁ capture indicates a non-direct contribution above E(³He) = 10 MeV, interpreted as a resonance due to a state with E_x = 25 ± 1 MeV, Γ_cm = 4 MeV, T = 1 (because the transition is E1, to a T = 0 final state) [the E1 radiative width |M|² ≥ 5.2/(2J + 1) W.u.], J^π = (2, 3, 4)^-, α + p + n parentage. The γ₄ resonance is interpreted as being due to a broad state at E_x = 26.6 MeV with T = 0. J^π = 3^- is consistent with the measured angular distribution. The ground and first excited state reduced widths for ³He + t parentage, θ₀² = 0.8 ± 0.2 and θ₁² = 0.6 ± 0.3: see (1974AJ01). See also (1985MOZZ, 1986MOZQ, 1987MO1I; theor.).

The angular distribution and polarization of the neutrons in reaction (b) have been measured at E(³He) = 2.70 and 3.55 MeV. The excitation function for E(³He) = 0.7 to 3.8 MeV decreases monotonically with energy. The excitation function for n₀ has been measured for E(³He) = 2 to 6 MeV and for E(³He) = 14 to 26 MeV; evidence for a broad structure at E(³He) = 20.5 ± 0.8 MeV is reported [⁶Li*(26.1)]: see (1979AJ01).

Angular distributions of deuterons (reaction (c)) have been measured for E_t = 1.04 to 3.27 MeV and at E(³He) = 0.29 to 32 MeV. Polarization measurements are reported for E_t = 9.02 to 17.27 MeV [see (1979AJ01)], as well as at E(pol. ³He) = 18.0 and 33.0 MeV (1986RA1C). See also (1986KO1K) and (1985CA41).

Elastic scattering (reaction (d)) angular distributions have been measured at E(³He) = 5.00 to 32.3 MeV and excitation functions have been reported for E(³He) = 4.3 to 33.4 MeV: see (1979AJ01). At the lower energies the elastic yield is structureless and decreases monotonically with energy. Polarization measurements are reported for E_t = 9.02 to 33.3 MeV. A strong change occurs in the analyzing power angular distributions at E_t = 15 MeV. A phase-shift analysis [single level R-matrix formalism, L ≤ 4] yields P-states [0^-, 2^-; T = 1] at E_x ≈ 21.5 and 21.0 MeV and F-states [3^-, 4^-; T = 1] at E_x ≈ 26.7 and 25.7 MeV. There is some indication also of T = 0, 3^-, 5^- and 3⁺ states at E_x ≈ 25, 29.5 and 31.5 MeV whose decay is presumably primarily by d + α: see (1979AJ01).

For other channels see (1984AJ01). See also (1984KR1B; theor.).

2. ³H(α, n)⁶Li Q_m = -4.7823

⁶Li*(0, 2.19) have been populated: see (1974AJ01). See also ⁷Li, (1983CO1E) and (1983FU11; theor.).

3. ³He(³He, π⁺)⁶Li Q_m = -123.792

Differential cross sections are reported for the transitions to ⁶Li*(0, 2.19) for E(³He) = 350, 420, 500 and 600 MeV (1983LE26). See also (1984AJ01), (1983BR31, 1983JA13) and (1984GE05; theor.).

4. ⁴He(d, γ)⁶Li Q_m = 1.4750

No resonance has been observed corresponding to formation of ⁶Li*(3.56) [0⁺; T = 1]: the parity-forbidden Γ_α ≤ 6 × 10^-7 eV (1984RO04). See also Table 6.2 (in PDF or PS).

The cross section for the capture cross section has been measured for E_α = 3 to 25 MeV by detecting the recoiling ⁶Li ions: the direct capture is overwhelmingly E2 with a small E1 contribution. The spectroscopic overlap between the ⁶Li_g.s. and α + d is 0.85 ± 0.04: see (1984AJ01). See also (1982KI11), (1985CA41, 1986LA22, 1986LA27) and (1984AK01, 1985AK1B, 1986AK1C, 1986BA1R; theor.).

5. (a) ⁴He(d, np)⁴He Q_m = -2.22459 E_b = 1.4750
(b) ⁴He(d, t)³He Q_m = -14.32049

Reaction (a) has been studied to E_α = 165 MeV and to E_d = 21.0 MeV: see (1979AJ01, 1984AJ01). Recent measurements are reported at E_{pol. d} = 5.4, 6.0 and 6.8 MeV (1985LU08; VAP, TAP), 6 to 11 MeV (1985OS02; VAP), 10.05 MeV (1983BR23; VAP, TAP) and 12.0 and 21.0 MeV (1983IS10; VAP, TAP) and at E_α = 11.3 MeV (1987BR07). It is clear that Coulomb effects need to be taken into account to understand the data. See also (1986DO1K).

(1986BR1N, 1986VUZZ, 1986VU1B, 1987VU1A; prelim.) have measured VAP and TAP at E_{pol. d} = 35 and 45 MeV in reaction (b). See also (1987GAZZ). For the earlier work, and for the other breakup channels, see (1974AJ01, 1979AJ01, 1984AJ01). See also (1988PUZZ) and (1983BA42, 1985DO03, 1986KO1J, 1987KA1M, 1987KUZI, 1987MI06, 1988KA1J, theor.).

6. ⁴He(d, d)⁴He E_b = 1.4750

Elastic differential cross-section and polarization measurements have been carried out up to E_α = 166 MeV and E_d = 45 MeV: see (1974AJ01, 1979AJ01, 1984AJ01). Recent measurements are reported at E_d = 0.87 to 1.43 MeV (1984BA19, 1985BAYZ; prelim.), at E_{pol. d} = 11.9 MeV (1988EL01; TAP), 21 MeV (see 1986MI1E; VAP, TAP), 24.0 and 38.2 MeV (1986GR1D; TAP; prelim.), 31.8 to 39.0 MeV (1986KO1M; TAP; prelim.), 56 MeV (1985NI01; VAP, TAP) and at E_α = 7.0 GeV/c (1984SA39). For a study of the inclusive inelastic scattering at E_α = 7.0 GeV/c see (1987BA13).

Phase-shift analyses, particularly that by (1983JE03) which uses all available differential cross section, vector and tensor analyzing power measurements and L ≤ 5, in the range E_d = 3 to 43 MeV lead to the results displayed in Table 6.3 (in PDF or PS). It is found that the d-wave shifts are split and exhibit resonances at E_x = 2.19 (³D₃), 4.7 (³D₂) and 5.65 MeV (³D₁). (1983JE03) suggest very broad G₃ and G₄ resonances at E_d = (19.3) and 33 MeV, a D₃ resonance at 22 MeV and F₃ and F₂ resonances at ≈ 34 and ≈ 39 MeV, corresponding to states which are primarily of (d + α) parentage.

(1985JE04) have investigated the points where A_yy = 1 and report four such points at E_d = 4.30 [θ_cm = 120.7°], 4.57 (58.0°), 11.88 (55.1°) and 36.0 ± 1.0 MeV (150.1 ± 0.3°). [For the latter see also (1986KO1M)]. The correspondence of these polarization maxima to ⁶Li states is discussed by (1985JE04). For a discussion of the M-matrix see (1988EL01). For recent work on (α + d) correlations involving ⁶Li*(0, 2.19, 4.31 + 5.65) see (1987CH08, 1987CH33, 1987PO03) and (1987FO08).

7. (a) ⁴He(³He, p)⁶Li Q_m = -4.0185
(b) ⁴He(³He, pd)⁴He Q_m = -5.49354

Angular distributions have been measured at E(³He) = 8 to 18 MeV and E_α = 42, 71.7 and 81.4 MeV: see (1974AJ01). At E_α = 28, 63.7, 71.7 and 81.4 MeV the α-spectra show that the sequential decay (reaction (b)) involves ⁶Li*(2.19) and possibly ⁵Li: see (1979AJ01).

8. (a) ⁴He(α, d)⁶Li Q_m = -22.3717
(b) ⁴He(α, pn)⁶Li Q_m = -24.5963
(c) ⁴He(α, αd)²H Q_m = -23.84674

Reactions (a) and (b) have been studied to E_α = 158.2 MeV [see (1979AJ01, 1984AJ01)] and at 198.4 MeV (1985WO11). The dependence of the cross section on energy shows that the α + α process does not contribute significantly to ⁶Li (and ⁷Li) synthesis above E_α = 250 MeV (1985WO11) [and see for additional comments on astrophysical problems]. For reaction (c) [and excited states of ⁴He] see (1984AJ01): ⁶Li*(2.19) is involved in the process.

10. (a) ⁶Li(γ, n)⁵Li Q_m = -5.67
(b) ⁶Li(γ, p)⁵He Q_m = -4.59
(c) ⁶Li(γ, d)⁴He Q_m = -1.4750
(d) ⁶Li(γ, t)³He Q_m = -15.7955

The (γ, n) and (γ, Xn) cross sections increase from threshold to a maximum at E_γ ≈ 12 MeV then decrease to E_γ = 32 MeV: see (1984AJ01) and (1988DI02). (1984DY01) also report a broad peak at 16 MeV. The cross section for photoproton production (reaction (b)) is generally flat up to 90 MeV. [The previously reported hump at E_γ ≈ 16 MeV is almost certainly due to oxygen contamination: see (1984AJ01).] See also (1988CA11) and ⁵He. The cross section for reaction (c) is ≤ 5 μb in the range E_γ = 2.6 to 17 MeV consistent with the expected inhibition of dipole absorption by isospin selection rules: see (1966LA04). The onset of quasideuteron photodisintegration between 25 and 65 MeV is suggested by the study of (1984WA18; E_bs = 67 MeV). The 90° differential cross section for reaction (d) decreases monotonically for E_γ = 18 to 70 MeV: reaction (d) contributes ≈ 1/3 of the total cross section for ⁶Li + γ, consistent with a ³H + ³He cluster description of ⁶Li_g.s. with θ² ≈ 0.68. The agreement with the inverse reaction, ³H(³He, γ) [see reaction 1] is good: see (1984AJ01). See also (1986LI1F).

The absorption cross section has been studied in the range E_γ ≈ 100 to 340 MeV; it shows a broad bump centered at ≈ 125 MeV and a fairly smooth increase to a maximum at ≈ 320 MeV: see (1984AJ01). For spallation studies see (1974AJ01, 1984AJ01). For pion production see (1986GL07, 1987GL01) and (1984AJ01). See also (1987GA22, 1987LI32, 1987PI06) and (1983BU1A, 1984BU1C, 1984IR1A, 1985LO02, 1985KO22, 1985VA1C, 1986AH03, 1986AK1B, 1986AV06, 1987BA2C, 1987BU04, 1987DU09, 1987LU1B, 1988BU1D; theor.).

The width, Γ_γ, of ⁶Li*(3.56) = 8.1 ± 0.5 eV: see (1974AJ01) and Table 6.4 (in PDF or PS) in (1979AJ01); E_x = 3562.88 ± 0.10 keV: see (1984AJ01). See also (1987PI06).

(b) ⁶Li(e, ep)⁵He Q_m = -4.59

The elastic scattering has been studied for E_e = 85 to 600 MeV: see (1974AJ01, 1979AJ01, 1984AJ01). The results appear to require that the ground state be viewed as an α-d cluster in which the deuteron cluster is deformed and aligned. The ground-state M1 current density has also been calculated (1982BE11). A model-independent analysis of the elastic scattering yields r_rms = 2.51 ± 0.10 fm. See also the discussion in (1984DO20).

Table 6.4 (in PDF or PS) here and Table 6.4 (in PDF or PS) in (1984AJ01) summarize the results obtained in the inelastic scattering of electrons. Form factors have been measured for ⁶Li*(2.19, 3.56, 5.37) as well as for the t + ³He continuum up to 4 MeV above threshold [no narrow structures corresponding to ⁶Li states are observed]: see (1984AJ01).

For reaction (b) see ⁵He and (1987VA08) and (1987VA1N). Angular distributions for the d₀ group in the (e, d₀) reaction have been measured for E_x = 10 to 28 MeV. The deduced E1 and E2 components of the (γ, d₀) cross section show no structure. The E1 strength implies non-negligible isospin mixing in this energy region (1986TA06). At E_e = 480 MeV (reaction (c)) the α-d momentum distribution in the ground state of ⁶Li has been studied. The results are well accounted for by an αNN model. The α-d probability in the ground state of ⁶Li is 0.73 [estimated ± 0.1]. The data are consistent with the expected 2S character of the α-d relative wave function (1986EN05). See also (1986EV1A). π⁰ production involving ⁶Li*(2.19, 3.56, 5.37) is reported at E_e = 500 MeV (1987NA1I; prelim.).

Elastic angular distributions have been measured at E_π⁺ ≈ 50 MeV [see (1984AJ01)] and at E_π^± = 100, 180 and 240 MeV (1986AN04; also to ⁶Li*(2.19)). Differential cross sections are also reported for E_π⁺ = 100 to 260 MeV to ⁶Li*(0, 2.19, 3.56, 4.25). The excitation function for the unnatural-parity transition to ⁶Li*(3.56) has an anomalous energy dependence (1984KI16).

Proton angular distributions have been measured for E_p = 0.5 to 800 MeV [p₀, p₁, p₂, p₃] [see (1966LA04, 1974AJ01, 1984AJ01)] and at E_{pol. p} = 5 to 17 MeV (1986PF1A; prelim.; p₀). Double-differential cross sections for the continuum yield [E_x = 1.5 - 3.5 MeV] are reported at E_p = 65 MeV (1987TO06; prelim.). See also (1983GLZZ, 1983PO1B, 1983POZX). For a summary of the results on excited states see Table 6.5 (in PDF or PS).

Reaction (b) has recently been studied at 70 MeV (1983GO06), at 50 - 100 MeV (1984PA1B, 1985PA1B; prelim.) and 1 GeV (1985BE30): see ⁵He and (1984AJ01) for the earlier work. Reaction (c) has been studied at E_p = 9 MeV to 1 GeV [see (1974AJ01, 1979AJ01, 1984AJ01)] and at 20 and 42 MeV (1983CA13) [report involvement of ⁶Li*(4.31, 5.65)], at 70 MeV (1983GO06, 1985PAZL, 1985PA04) and at 119.6 and 200.2 MeV (1984WA09, 1985WA25). In the latter experiments the spectroscopic factors for ⁶Li_g.s. are deduced to be 0.76 [at 119.6 MeV] and 0.84 [at 200.2 MeV] using DWIA and a bound-state Woods-Saxon 2S wave function (1984WA09, 1985WA25).

Work on reaction (d) has suggested that the ³He + t parentage of ⁶Li is comparable with the α + d parentage: see (1984AJ01). See also (1985PAZL). For reaction (e) see ⁵Li, ⁶Be and (1985BE30). The (p, 3p) reaction has been studied by (1984NA17). For antiproton studies see (1987AS06) and the "GENERAL" section here. See also (1984AJ01) for the earlier work and ⁷Be, (1983AN18, 1986SA1Q, 1987GAZM, 1987SA46, 1988MIZX), (1984LA33, 1985AL16, 1986CH1J, 1986WA11, 1987LE33) and (1982CH28, 1983GO17, 1983KA1A, 1983SM04, 1984GU14, 1984KO1E, 1984KU03, 1984KU06, 1984MU01, 1985BE60, 1985DO16, 1985KA1D, 1985PA03, 1986CHZX, 1986IM1A, 1986IM01, 1986OS08, 1986VL1A, 1986ZH03, 1987FA1H, 1987HA01, 1987IM1F, 1987IM04, 1987VD01, 1987ZH1D, 1988CH06, 1988VD1A; theor.).

(c) ⁶Li(d, 2d)⁴He Q_m = -1.4750
(d) ⁶Li(d, αp)³H Q_m = 2.5577

Angular distributions of deuterons have been measured at E_d = 4.5 to 19.6 MeV [see (1979AJ01)] and at 50 MeV (1988KO1C; prelim.). The T = 1, 0⁺ state, ⁶Li*(3.56) is not appreciably populated. For a summary of the results on excited states see Table 6.5 (in PDF or PS).

At E_d = 21 MeV reaction (b) shows spectral peaking (characteristic of ¹S₀ for the pn system [T = 1]) when ⁶Li*(3.56) is formed, in contrast with the much broader shape (characteristic of ³S₁) seen when ⁶Li*(0, 2.19) are populated. A study of reaction (c) at E_d = 52 MeV shows that the α-clustering probability, N_eff = 0.12^+0.12_-0.06 if a Hankel function is used. The α-particle and the deuteron clusters in ⁶Li have essentially a relative orbital momentum of l = 0. The D-state probability of the ground state of ⁶Li is ≈ 5% of the S-state. Quasi-free scattering is an important process even for E_d = 6 to 11 MeV. Interference effects are evident in reaction (c) proceeding through ⁶Li*(2.19, 4.31): this is due to the experiment being unable to determine whether the detected particle was emitted first or second in the sequential decay. Reactions (c) and (d) studied at E_d = 7.5 to 10.5 MeV indicate that the three-body breakup of ⁶Li at these low energies is dominated by sequential decay processes. See (1979AJ01) for references.

Reaction (b) has been studied at E_α = 6.6 to 700 MeV: see (1974AJ01, 1979AJ01, 1984AJ01). At the latter energy and using a width parameter of 60.6 MeV/c the effective number of α + d clusters for ⁶Li_g.s., n_eff = 0.98 ± 0.05. The results are very model dependent: see (1984AJ01). At E_α = 27.2 MeV ⁶Li*(2.19) is very strongly populated (1985KO29). See also (1982CH28, 1983AV02, 1983BE51, 1983BU15, 1985BE60, 1986GA1F, 1986ZE01, 1987KO1L, 1988LE06; theor.).

Reaction (b) has been studied for E(⁶Li) = 36 to 47 MeV: enhancements in yield, due to double spectator poles, have been observed in d-d and α-α but not in α-d double coincidence spectra. The widths of the peaks are smaller than those predicted from the momentum distribution of α + d clusters in ⁶Li. ⁶Li*(2.19) was also populated. See references in (1984AJ01).

(b) ⁷Li(p, pn)⁶Li Q_m = -7.250

Angular distributions of deuterons (reaction (a)) have been studied for E_p = 167 to 800 MeV [see (1979AJ01, 1984AJ01)] and at 18.6 MeV (1986GO23, 1987GO27; d₀, d₁, d₂; see for spectroscopic factors), 200 and 400 MeV (1985KR13; d₀, d₁; d₂ is weakly populated at 200 MeV) and at 800 MeV (1984SM04; d₀, d₁). The ratio of the intensities of the groups to ⁶Li*(2.19) and ⁶Li_g.s. increases with energy. It is suggested that this can be understood in terms of a small admixture of 1f orbital in these states (1985KR13). A DWBA analysis of E_p = 185 MeV data leads to C²S= 0.87, 0.67, 0.24, (0.05), 0.14, respectively for ⁶Li*(0, 2.19, 3.56, 4.31, 5.37). No other states were seen below E_x ≈ 20 MeV: see (1979AJ01). In reaction (b) at E_p = 1 GeV the separation energy between ≈ 6.5 MeV broad 1p_3/2 and 1s_1/2 groups is reported to be 18.0 ± 0.8 MeV (1985BE30, 1985DO16). See also (1983LY04, 1988BE1I, 1988GUZW; theor.).

32. ⁷Li(d, t)⁶Li Q_m = -0.993

A study at E_d = 23.6 MeV of the relative cross sections of the analog reactions ⁷Li(d, t)⁶Li (to the first two T= 1 states at 3.56 and 5.37 MeV) and ⁷Li(d, ³He)⁶He (to the ground and 1.80 MeV excited states) shows that ⁶Li*(3.56, 5.37) have high isospin purity (α² < 0.008): this is explained in terms of antisymmetrization effects which prevent mixing with nearby T= 0 states: see (1979AJ01). (1987BO39) [E_d = 30.7 MeV] deduce that the branching ratio of ⁶Li*(4.31) [2⁺] into a dinucleon [T= 1, S= 0] is (85 ± 10)%: see also reactions 13 in ⁶He and 4 in ⁶Be. See also (1987GUZZ; E_d = 18 MeV; angular distributions to ⁶Li*(0, 2.19, 3.56); prelim.) and (1984BL21, 1986AV01, 1988GUZW; theor.).

33. (a) ⁷Li(³He, α)⁶Li Q_m = 13.328
(b) ⁷Li(³He, dα)⁴He Q_m = 11.8527

Angular distributions have been reported at E(³He) = 5.1 to 33.3 MeV [see (1974AJ01, 1984AJ01): the lower energy work has not been published]. Excited states observed in this reaction are displayed in Table 6.5 (in PDF or PS). No other states are reported below E_x = 10 MeV: see (1979AJ01). (1986AN04) have analyzed unpublished data which suggest the involvement of several broad highly excited states of ⁶Li. See also (1987AL23).

Several attempts have been made to look at the isospin decay of ⁶Li*(5.37) [J^π; T= 2⁺; 1] via ⁷Li(³He, α)⁶Li* -→ d + α: the branching is < 1%. Γ_p/Γ = 0.35 ± 0.10 and Γ_p+n/Γ = 0.65 ± 0.10 for ⁶Li*(5.37): see (1979AJ01). ⁴He + d spectra suggest the excitation of ⁶Li*(4.3) [E_x = 4.3 ± 0.2 MeV, Γ = 1.6 ± 0.3 MeV] and ⁶Li*(5.7) [E_x = 5.65 ± 0.2 MeV, Γ = 1.65 ± 0.3 MeV]: see (1984AJ01). See also (1985DA29). At E(³He) = 120 MeV the missing mass spectra for (³He, 2d) and (³He, pt) reflects the population of ⁶Li*(0, 2.19) and suggests broad structures at E_x = 28.5 and 32.9 MeV (1985FR01). See also ¹⁰B, (1988BO1J) and (1983KU17; theor.).

34. (a) ⁷Li(⁶Li, ⁷Li)⁶Li
(b) ⁷Li(⁷Li, ⁸Li)⁶Li Q_m = -5.217

At E(⁶Li) = 93 MeV a broad group (Γ ≈ 11 MeV) centered at E_x = 20 MeV is reported in addition to other peaks at E_x = 17.1 ± 0.3, 18.9 ± 0.3 and 21.2 ± 0.3 MeV (1987GLZW; prelim.). See (1984KO25) for reaction (b).

35. (a) ⁹Be(p, α)⁶Li Q_m = 2.126
(b) ⁹Be(p, 2α)²H Q_m = 0.651
(c) ⁹Be(p, pt)⁶Li Q_m = -17.688

Angular distributions of α-particles (reaction (a)) have been measured at E_p = 0.11 to 45 MeV [see (1974AJ01, 1979AJ01)] and at E_p = 22.5, 31 and 41 MeV (1986HA27; α₀, α₁, α₂; see for spectroscopic factors). See also Table 6.5 (in PDF or PS) and (1984AJ01). ⁶Li*(3.56) decays by γ-emission consistent with M1; Γ_α/Γ < 0.025 [forbidden by spin and parity conservation]: see (1984AJ01). At E_p = 9 MeV the yield of reaction (b) is dominated by FSI through ⁸Be*(0, 2.9) and ⁶Li*(2.19) with little or no yield from direct three-body decay: see (1979AJ01). Reactions (b) and (c) at E_p = 58 MeV involve ⁶Li*(0, 2.19) (1985DE17). See also ¹⁰B, (1986AN26) and (1985MAZG, 1986KA26; theor.).

36. ⁹Be(d, ⁵He)⁶Li Q_m = -9.92

37. ⁹Be(t, ⁶He)⁶Li Q_m = -5.381

Angular distributions of ⁶He_g.s. + ⁶Li_g.s. and ⁶He_g.s. + ⁶Li*_3.56 [both listed ions were detected] have been measured at E_t = 21.5 and 23.5 MeV. In the latter case the final state is composed of two isobaric analog states: angular distributions are symmetric about 90° cm, within the overall experimental errors. In the reaction leading to the ground states of ⁶He and ⁶Li differences from symmetry of as much as 40% are observed at forward angles. Angular distributions involving ⁶He_g.s. + ⁶Li*(2.19) and ⁶Li_g.s. + ⁶He*(1.8) have also been measured. This reaction appears to proceed predominantly by means of the direct pickup of a triton or ³He from ⁹Be. Differential cross sections are also reported at E_t = 17 MeV: see (1984AJ01) for references.
