1. (a) 3He(3H, γ)6Li Qm = 15.7955
(b) 3He(3H, n)5Li Qm = 10.13 Eb = 15.7955
(c) 3He(3H, d)4He Qm = 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 Ex = 25 ± 1 MeV, Γcm = 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.], Jπ = (2, 3, 4)-, α + p + n parentage. The γ4 resonance is interpreted as being due to a broad state at Ex = 26.6 MeV with T = 0. Jπ = 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 Et = 1.04 to 3.27 MeV and at E(3He) = 0.29 to 32 MeV. Polarization measurements are reported for Et = 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 Et = 9.02 to 33.3 MeV. A strong change occurs in the analyzing power angular distributions at Et = 15 MeV. A phase-shift analysis [single level R-matrix formalism, L ≤ 4] yields P-states [0-, 2-; T = 1] at Ex ≈ 21.5 and 21.0 MeV and F-states [3-, 4-; T = 1] at Ex ≈ 26.7 and 25.7 MeV. There is some indication also of T = 0, 3-, 5- and 3+ states at Ex ≈ 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 Qm = -4.7823

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

3. 3He(3He, π+)6Li Qm = -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 Qm = 1.4750

No resonance has been observed corresponding to formation of 6Li*(3.56) [0+; T = 1]: the parity-forbidden Γα ≤ 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 Eα = 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 6Lig.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 Qm = -2.22459 Eb = 1.4750
(b) 4He(d, t)3He Qm = -14.32049

Reaction (a) has been studied to Eα = 165 MeV and to Ed = 21.0 MeV: see (1979AJ01, 1984AJ01). Recent measurements are reported at Epol. 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 Eα = 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 Epol. 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 Eb = 1.4750

Elastic differential cross-section and polarization measurements have been carried out up to Eα = 166 MeV and Ed = 45 MeV: see (1974AJ01, 1979AJ01, 1984AJ01). Recent measurements are reported at Ed = 0.87 to 1.43 MeV (1984BA19, 1985BAYZ; prelim.), at Epol. 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 Eα = 7.0 GeV/c (1984SA39). For a study of the inclusive inelastic scattering at Eα = 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 Ed = 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 Ex = 2.19 (3D3), 4.7 (3D2) and 5.65 MeV (3D1). (1983JE03) suggest very broad G3 and G4 resonances at Ed = (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 Ayy = 1 and report four such points at Ed = 4.30 [θcm = 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).

Angular distributions have been measured at E(3He) = 8 to 18 MeV and Eα = 42, 71.7 and 81.4 MeV: see (1974AJ01). At Eα = 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 Qm = -22.3717
(b) 4He(α, pn)6Li Qm = -24.5963
(c) 4He(α, αd)2H Qm = -23.84674

Reactions (a) and (b) have been studied to Eα = 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 Eα = 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.

9. 6He(β-)6Li Qm = 3.507

See reaction 1 in 6He.

(b) 6Li(γ, p)5He Qm = -4.59
(c) 6Li(γ, d)4He Qm = -1.4750
(d) 6Li(γ, t)3He Qm = -15.7955

The (γ, n) and (γ, Xn) cross sections increase from threshold to a maximum at Eγ ≈ 12 MeV then decrease to Eγ = 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 Eγ ≈ 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 Eγ = 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; Ebs = 67 MeV). The 90° differential cross section for reaction (d) decreases monotonically for Eγ = 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 6Lig.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 Eγ ≈ 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).

The elastic scattering has been studied for Ee = 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 rrms = 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 Ex = 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 Ee = 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 Ee = 500 MeV (1987NA1I; prelim.).

Elastic angular distributions have been measured at Eπ+ ≈ 50 MeV [see (1984AJ01)] and at Eπ± = 100, 180 and 240 MeV (1986AN04; also to 6Li*(2.19)). Differential cross sections are also reported for Eπ+ = 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 Ep = 0.5 to 800 MeV [p0, p1, p2, p3] [see (1966LA04, 1974AJ01, 1984AJ01)] and at Epol. p = 5 to 17 MeV (1986PF1A; prelim.; p0). Double-differential cross sections for the continuum yield [Ex = 1.5 - 3.5 MeV] are reported at Ep = 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 Ep = 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 6Lig.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.).

Angular distributions of deuterons have been measured at Ed = 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 Ed = 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 Ed = 52 MeV shows that the α-clustering probability, Neff = 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 Ed = 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 Ed = 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.

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., neff = 0.98 ± 0.05. The results are very model dependent: see (1984AJ01). At Eα = 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).

Reaction (b) at 0.9 GeV involves 6Li*(2.19) (1985RE1A; prelim.). See also 7Li, (1986GO1M) and (1985ST1A, 1986BA2G; theor.).

30. 7Li(π+, p)6Li Qm = 133.101

Differential cross sections have been measured at Eπ+ = 75 and 175 MeV for the transitions to 6Li*(0, 2.19): see (1984AJ01).

31. (a) 7Li(p, d)6Li Qm = -5.025
(b) 7Li(p, pn)6Li Qm = -7.250

Angular distributions of deuterons (reaction (a)) have been studied for Ep = 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 6Lig.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 Ep = 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 Ex ≈ 20 MeV: see (1979AJ01). In reaction (b) at Ep = 1 GeV the separation energy between ≈ 6.5 MeV broad 1p3/2 and 1s1/2 groups is reported to be 18.0 ± 0.8 MeV (1985BE30, 1985DO16). See also (1983LY04, 1988BE1I, 1988GUZW; theor.).

32. 7Li(d, t)6Li Qm = -0.993

A study at Ed = 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) [Ed = 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; Ed = 18 MeV; angular distributions to 6Li*(0, 2.19, 3.56); prelim.) and (1984BL21, 1986AV01, 1988GUZW; theor.).

33. (a) 7Li(3He, α)6Li Qm = 13.328
(b) 7Li(3He, dα)4He Qm = 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 Ex = 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) [Jπ; T= 2+; 1] via 7Li(3He, α)6Li* -→ d + α: the branching is < 1%. Γp/Γ = 0.35 ± 0.10 and Γp+n/Γ = 0.65 ± 0.10 for 6Li*(5.37): see (1979AJ01). 4He + d spectra suggest the excitation of 6Li*(4.3) [Ex = 4.3 ± 0.2 MeV, Γ = 1.6 ± 0.3 MeV] and 6Li*(5.7) [Ex = 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 Ex = 28.5 and 32.9 MeV (1985FR01). See also 10B, (1988BO1J) and (1983KU17; theor.).

34. (a) 7Li(6Li, 7Li)6Li

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

Angular distributions of α-particles (reaction (a)) have been measured at Ep = 0.11 to 45 MeV [see (1974AJ01, 1979AJ01)] and at Ep = 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; Γα/Γ < 0.025 [forbidden by spin and parity conservation]: see (1984AJ01). At Ep = 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 Ep = 58 MeV involve 6Li*(0, 2.19) (1985DE17). See also 10B, (1986AN26) and (1985MAZG, 1986KA26; theor.).

36. 9Be(d, 5He)6Li Qm = -9.92

37. 9Be(t, 6He)6Li Qm = -5.381

Angular distributions of 6Heg.s. + 6Lig.s. and 6Heg.s. + 6Li*3.56 [both listed ions were detected] have been measured at Et = 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 6Heg.s. + 6Li*(2.19) and 6Lig.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 Et = 17 MeV: see (1984AJ01) for references.
