^{7}Be (2002TI10)(See Energy Level Diagrams for ^{7}Be) GENERAL: References to articles on general properties of ^{7}Be published since the previous review (1988AJ01) are grouped into categories and listed, along with brief descriptions of each item, in the General Tables for ^{7}Be located on our website at (nucldata.tunl.edu/NuclData/General_Tables/7be.shtml). See also 3 [Electromagnetic Transitions in A = 57] (in PDF or PS) and 7.7 [Table of Energy Levels] (in PDF or PS). The interaction nuclear radius of ^{7}Be is 2.22 ± 0.02 fm (1985TA18). [See also for derived nuclear matter, charge and neutron matter r.m.s. radii]. A measurement of the magnetic moment by (1998KAZN) gave a preliminary result μ_{l} = 1.398 ± 0.015 μ_{N}.
The εcapture decay is complex: see reaction 33 in ^{7}Li.
The capture cross sections have been measured for E_{α} = 0.250 to 5.80 MeV and at E(^{3}He) = 19 to 26 MeV [see (1974AJ01, 1984AJ01)], at E_{cm} = 195 to 686 keV (1988HI06), and at E_{α} = 385 to 2728 keV (1984OS03) and 1225 keV (1984AL24). One of the main reasons for doing these measurements is to determine the astrophysical S(0) factor. The values of S(0) appear, on the average, to be higher if the experiment involves measurement of the 0.48 MeV γ following εcapture rather than if it involves a direct measurement of the capture γrays. It is not entirely clear why this should be so. Contaminant production of ^{7}Be may be involved: see (1988HI06) and e.g. (1984AL24, 1985FI1D, 1986LA22). Earlier measurements, sometimes recalculated, are discussed by (1986LA22, 1987KA1R, 1988HI06). The latter adopt best values of S(0) = 0.51 ± 0.02 keV b [prompt γrays] and 0.58 ± 0.02 keV b [^{7}Be activity] (1988HI06). See also (1984AL24, 1985FI1D, 1987KA1R, 1988BA86). More recently, (1993MO11) measured differential cross sections for ^{3}He  α scattering for E_{lab}(^{3}He) < 3 MeV and obtained optical potentials which were used to calculate S(0) for the capture reaction. They obtained S(0) = 0.516 keV · b in agreement with (1988HI06). They also calculated the branching ratio for transition to the first excited state and ground state to be R = 0.43. Theoretical calculations are in general agreement with the experimental values. See (1988AJ01) for examples from some of the early work. Calculations of astrophysical S factors for the capture reaction are included in (1988BU17, 1988KA07, 1989CH37, 1989CH48, 1989KA18, 1995DU09, 1995LI07, 1997DU15, 2001NO04). Phase shifts and cross sections (E_{cm} < 5 MeV) were calculated in an extended twocluster model by (2000CS06). Astrophysical S factors were deduced. See also the Sfactor calculation of (2001CS03). The reaction rate at T = 300 K was calculated in (1989SC25). See also the related work of (1990SC16, 1990SC26). The reaction rate and the effects of electron screening on the solar neutrino flux has been calculated by (2000LI13). The reaction rate and a correction to the Gamow penetration factor were calculated by (1994KA02). See also the calculations described in (1998FI02, 1999BU10, 1999SH13, 2000BA09). As noted in (1988AJ01), the solar model calculations of (1982BA80) used S_{34}[S(0)] = 0.52 ± 0.02 keV · b. It appears clear that the uncertainty in S_{34} is not of severe consequence to the solar neutrino problem [see, e.g. (1985FI1D)]. For other early astrophysicalrelated work see (1984AJ01, 1988AJ01). See also (1986LI04).
Elasticscattering studies have been reported for E = 0.25 to 198.4 MeV [see (1974AJ01, 1979AJ01, 1984AJ01)] and at E_{α} = 56.3 to 95.5 MeV (1985NE08, 1986YA14). Analyzing power measurements have been carried out at E = 4.3 to 98 MeV [see (1979AJ01)] and at E(^{3}He) = 55 to 95 MeV (1986YA14). For l ≤ 4, only fwave phase shifts show resonance structure for E(^{3}He) < 18 MeV, corresponding to ^{7}Be*(4.57, 6.73, 9.27): see 7.8 (in PDF or PS). No structure corresponding to ^{7}Be*(7.21) (J^{π} = 5/2^{}) is seen in the elastic data. The swave phase shift is somewhat greater than hardsphere. The decay of ^{7}Be*(9.27) (J^{π} = 7/2^{}) to ^{6}Li_{g.s.} requires fshell configuration admixture. An estimate of the yield of groundstate protons relative to those corresponding to ^{6}Li*(2.19) yields γ^{2}(p_{0})/γ^{2}(p_{1}) = (16^{+5}_{10})% (1967SP10). A phaseshift analysis (singlelevel Rmatrix) has been carried out for E(^{3}He) = 18 to 32 MeV: the pwave phase shifts indicate a 1/2^{} state at E_{x} ≈ 16.7 MeV (E_{r} = 26.4 MeV), with Γ = 6.5 MeV (1978LU05). An Rmatrix and Smatrix analysis (1992ZU03) of elastic scattering at E_{α}(cm) = 11  41 MeV on a polarized ^{3}He target gave evidence of broad 9/2^{+} and 11/2^{} resonances. The Rmatrix centerofmass resonance energies and widths for the 9/2^{+} and 11/2^{} resonances are E_{res} = 29.5 ± 1.0 MeV, Γ = 8.5 ± 2.5 MeV and E_{res} = 32.5 ± 1.5 MeV, Γ = 10.5 ± 3.0 MeV, respectively (see 7.9 (in PDF or PS)). See also the earlier analysis reported in (1989OS06). Differential cross sections were measured for E(^{3}He) = 1  3 MeV by (1993MO11). The data together with other available data were analyzed, and the optical potentials obtained were used to calculate astrophysical S factors for the radiative capture reaction (see reaction 1). The differential cross section for reaction (b) has been determined for E(^{3}He) = 8 to 28 MeV [see (1979AJ01)] and at E_{α} = 22.2 to 26.5 MeV. Resonances are observed corresponding to ^{7}Be*(7.21, 9.27) in the p_{0} yield, to ^{7}Be*(9.27) in the p_{1} yield and to states at E_{x} ≈ 10 MeV (T = 1/2) and 11.0 MeV (T = 3/2) in the yield of 3.56 MeV γrays. The evidence for the latter derives mainly from interference arguments. There is also some evidence for an extremely broad J^{π} = 1/2^{} structure at E_{x} ≥ 10 MeV [see also ^{6}Li(p, p): reaction 6]: see 7.8 (in PDF or PS) and (1974AJ01, 1984AJ01). For α + ^{3}He correlations see (1987PO03). See also the General Table for ^{7}Be located on our website at (nucldata.tunl.edu/NuclData/General_Tables/7be.shtml). For elastic and inelastic inclusive scattering cross sections at p_{α} = 7.0 GeV/c see (1984SA39, 1987BA13). See also (1984IW01; astrophys.). References to early theoretical work on ^{3}He + ^{4}He reactions are given in (1988AJ01). More recent theoretical studies include: an RGM study of the d + ^{5}He cluster configuration (1991FU02); a potential description of cluster channels (1993DU02); inversion of phase shifts and ^{7}Be boundstate energies to obtain potentials (1994CO08); a calculation of ^{7}Be charge form factors (1987RO24); microscopic cluster theory (1987TA06); Glauber amplitude expansion calculation of σ(θ) (1988CH16, 1990LI11); a calculation of scattering lengths and astrophysical S factors (1988CH47, 1989CH34); a study of potentials deduced from phase shifts (1995MA37); and a multiconfiguration RGM calculation of reaction cross sections (1995FU16).
Angular distributions have been reported at E_{α} = 61.5 to 158.2 MeV (1982GL01) and 198.4 MeV (1985WO11) for the transitions to ^{7}Be*(0 + 0.43). Cross section measurements at E_{α} = 160, 280, 620 MeV are reported in (2001ME13). See also (2001AU06). Thermonuclear reaction rates for this reaction calculated from evaluated data are presented in the compilation (1999AN35).
At low energies (E_{p} = 0.2 to 1.2 MeV) gamma transitions to the ground (γ_{0}) and to the 0.43 MeV (γ_{1}) states have been observed. The yield shows no resonance and the branching ratio remains approximately constant at 61 ± 5% to the ground state and 39 ± 2% to ^{7}Be*(0.43): see (1974AJ01, 1984AJ01). Angular distributions of γ_{0} and γ_{1} have been studied at E_{p} = 0.50, 0.80 and 1.00 MeV (1987TI05). At E_{p} = 44.4 MeV, ^{7}Li*(4.57) is strongly populated (1985HA05). See also (1983OS04), (1983HA1B, 1984BO1C, 1985CA41; astrophys.) and (1985BL1B). In other work, γ angular distributions and γtochargedparticle ratios were measured for E_{p} = 40  180 keV and used to deduce astrophysical S factors (1992CE02). See also the measurements at E_{p} = 30  180 keV of (1993BRZQ). Measurements of thicktarget yields and analyzing power versus θ were made with 80 keV polarized beams and used to deduce relative sp wave contributions and astrophysical S factors (1996LA10). The slope of the astrophysical S factor was deduced from measurements at E_{p} = 80, 95 and 110 keV (1999KEZY). See also the cross section measurements at E_{p} = 0.8 MeV of (2000SK02). A compilation and review of Coulomb dissociation experiments of astrophysical significance is presented in (1996RE16). Reaction rates for E_{p} < 2 MeV were analyzed by (1997NO04). The primordial ^{6}Li component was deduced. A compilation of chargedparticle induced thermonuclear reaction rates is presented in (1999AN35). Cross section measurements at E_{p} = 0.8 MeV are reported by (2000SK02).
The previous review (1988AJ01) notes that measurements of elastic angular distributions have been reported for E_{p} = 0.5 to 600 MeV: see (1966LA04, 1974AJ01) and ^{6}Li. Two resonances are reported at E_{p} = 1.84 and 5 MeV in the elastic yield [^{7}Be*(7.21, 9.9)]. The parameters of the lower resonance are shown in 7.4 (in PDF or PS). The 5MeV resonance has Γ ≈ 1.8 MeV and appears to also be formed by pwaves: γ^{2}_{p} is then 3 ± 2 MeV fm. A weak rise near E_{p} = 8 to 9 MeV may indicate a further level, ^{7}Be* ≈ 13 MeV. A broad resonance at E_{p} = 14 MeV has also been suggested. Polarization measurements have been carried out for E_{p} = 1.2 to 800 MeV [see (1974AJ01, 1979AJ01, 1984AJ01)] and at E_{p} = 4 to 10 MeV (1986BE1H; p_{0}) and 25 and 35 MeV (1982ROZT, 1983PO1B, 1983POZX; p_{0}, p_{1}). A phaseshift analysis for E_{p} = 0.5 to 5.6 MeV shows that only ^{2}S, ^{4}S and ^{4}P are involved. The ^{4}P_{5/2} amplitude resonates at E_{p} = 1.8 MeV, and the broad resonance at 5 MeV can be reproduced equally well by either ^{4}P_{3/2} or ^{4}P_{1/2}: tensor polarization measurements are necessary to distinguish between the two: see (1974AJ01). In more recent work, cross sections and analyzing powers were measured at E_{p} = 1.6  10 MeV (1989HA17), at E_{p} = 200 MeV (1990GL04) and at E_{p} = 0.4  2.2 MeV (1995SK01). Parameters for the E_{p}(lab) = 1.8 MeV resonance were measured by (1995SK01) (see 7.10 (in PDF or PS)). The depolarization parameter was measured at E_{p} = 72 MeV (1994HE11). The reaction cross section for formation of ^{6}Li*(2.19) has been measured for E_{p} = 3.6 to 9.40 MeV: a broad resonance indicates the presence of a state with E_{x} ≈ 10 MeV, Γ = 1.8 MeV, J^{π} = (3/2, 5/2)^{}, T = 1/2. The crosssection and angular distributions of p_{2} (^{6}Li*(3.56)) for E_{p} = 4.26 to 9.40 MeV are analyzed in terms of two J^{π} = 3/2^{} states at E_{x} ≈ 10 and 11 MeV: see reaction 3. The total cross section for formation of ^{6}Li*(3.56) decreases slowly with energy for E_{p} = 24.3 to 46.4 MeV. The total reaction cross section has been measured for E_{p} = 25.0 to 48 MeV (1985CA36). K^{y}_{y} spectra at E_{p} = 50, 65 and 80 MeV, θ = 3°  20°, are reported by (1987SA46). For the inclusive cross section at E_{p} = 200 MeV [back angles] see (1984AV07). See also the measurement of cross sections and analyzing powers for excitation of ^{6}Li*(2.18, 3.56) at E_{p} = 200 MeV (1990GL04). Theoretical work on this reaction published since the previous review (1988AJ01) includes: a foldingmodel calculation to deduce halo effects (1992GA27); selfconsistent calculation with mattercluster dynamic model (1992KA06); a potential description study with a supermultiplet symmetry approximation (1993DU09); a description with a microscopic effective interaction (1993KO44); a consistent foldingmodel description (1993PE13); a calculation for (p, p) and (p, p') with GlauberSitenko diffraction theory (1994ZH28, 1994ZH34); an analysis with phenomenological microscopic optical potentials (1995GA24); a consistent analysis of the analyzing power puzzle (1995KA03); a continuumcontinuum coupling analysis (1995KA07); a fullymicroscopic analysis at E_{p} = 200 MeV (1997DO01); an RGM study of a 5/2^{} resonance (1997IG04); a study of shellmodel structures observed in proton and electron scattering (1997KA24); and a microscopicmodel analysis for E_{p} = 65 MeV (1998DO16).

The yield of neutrons increases approximately monotonically from threshold to E_{p} = 14.3 MeV: see (1974AJ01). The transverse polarization transfer, D_{NN} (0°), for the g.s. transition has been measured for E_{p} = 30 to 160 MeV: see (1984TA07, 1986TA1E) and ^{6}Be. Analyzingpower measurements are reported at E_{p} = 50 and 80 MeV (1987SA46) and at 52.8 MeV (1988HE08) [K^{y'}_{y} (0°) = 0.33 ± 0.04; also K^{z'}_{z}]. See also (1986MC09; E_{p} = 800 MeV) and (1984BA1U, 1986RA21, 1986SA1Q). For more recent work see the discussion on this reaction under ^{6}Be.
Thermonuclear reaction rates and the astrophysical Sfactor have been derived from the lowenergy (E_{p} < 0.7 MeV) cross section measurements: S(0) ≈ 3.1 MeV b: see (1974AJ01, 1979AJ01, 1984AJ01). At higher energies the cross section exhibits a broad, low maximum near E_{p} = 1 MeV and a pronounced resonance at E_{p} = 1.85 MeV (Γ < 0.5 MeV). No other structure is reported up to E_{p} = 5.6 MeV. Measurements between E_{p} = 0.4 and 3.4 MeV show that the polarizations are generally large and positive: see (1974AJ01). Angular distributions have been reported for E_{p} = 0.15 to 45 MeV [see (1974AJ01, 1979AJ01, 1984AJ01)] and at 47.8, 53.5, 58.5 and 62.5 MeV (1984NE05). For other early work see references cited in (1988AJ01). More recently, measurements of analyzing power versus E_{p} for E_{p} = 180  280 keV were reported by (1991BU14). Tests of isotopic dependence of electronscreening effects on the astrophysical S factor were reported for E_{cm} = 10  1004 keV (1992EN01, 1992EN04). See also: an analysis of Sfactor data for E_{cm} = 10  1000 keV (1992SO25); a study of atomic screening and other small effects in reaction rates (1997BA95); a study of screening effects for solid targets (1997BO12); an opticalmodel formulation and S factor calculation for E = 10  100 keV (1997KI02); a study of reaction rates and the primordial ^{6}Li component (1997NO04); and a study of Rmatrix parameterization for E_{cm} < 1 MeV (1998AN18). Thermonuclear reaction rates for this reaction calculated from evaluated data are presented in the compilation (1999AN35).
Angular distributions of the n_{0} and n_{1} groups have been measured at E_{d} = 0.20 to 15.25 MeV: see (1974AJ01, 1979AJ01). The n_{1}  γ correlations are isotropic, indicating J^{π} = 1/2^{} for ^{7}Be*(0.43). Broad maxima are observed in the ratio of lowenergy to highenergy neutrons at E_{d} = 4.2 and 5.1 MeV [^{7}Be*(6.5, 7.2), Γ_{cm} = 1.2 and 0.5 MeV, respectively]: see (1966LA04). See also ^{8}Be in (1988AJ01) and (1988KO1C). Measurements at E < 1 MeV and determination of the astrophysical Sfactor as well as studies of the (d, n)/(d, p) ratio are described in (1993CZ01, 1997CZ04). Cross section measurements and Sfactor determinations at E_{d} = 24  111 keV are reported in (2001HO23). A calculation of the (d, n)/(d, p) branching ratio and discussions of the rate of Coulombinduced predissociation is presented in (1990KO26). Cross sections for E < 1 MeV were calculated and reaction rates were deduced by (2001VO02). Calculations of radiated power vs. plasma temperature in controlled fusion are described in (1999HA50). See also (1996BO27, 1997NO04).
Angular distributions of the d_{0} and d_{1} groups to ^{7}Be*(0, 0.43) have been measured at E(^{3}He) = 8, 10, 14 and 18 MeV and at E(^{3}He) = 33.3 MeV [^{7}Be*(4.57) is also populated]: see (1974AJ01, 1984AJ01).
The reaction was used by (1998NA14) to separate ΔS = 0 and ΔS = 1 transitions through coincidence measurements of γrays from the ^{7}Be 0.43 MeV state.
Forwardangle differential cross sections have been measured at E_{π+} = 20 MeV (1987IR01; also at 155° and 166°), at 33.5, 41.1, 48.7 and 58.8 MeV (1985IR01, 1985IR02), 70 to 180 MeV [see (1984AJ01)] and from 300 to 550 MeV (1988RO03). A Glaubermodel analysis of σ(θ) for E = 250  650 MeV is described in (1990OS01). Model calculations of cross sections and polarization observables are presented in (1999NO02).
The excitation energy of ^{7}Be*(0.43) is 429.20 ± 0.10 keV, τ_{m} = 192 ± 25 fsec: see (1979AJ01). Angular distributions of n_{0} and n_{1} have been reported at E_{p} = 1.9 to 119.8 MeV [see (1974AJ01, 1979AJ01, 1984AJ01)] and at 200, 300 and 400 MeV (1987WAZT; n_{0+1}). ^{7}Be*(4.55, 6.51, 7.19, 10.79) have also been populated: see (1974AJ01, 1979AJ01). The ratios of σ_{1}/σ_{0} (^{7}Be*(0.43)/^{7}Be_{g.s.}) have been measured at 24.8, 35 and 45 MeV and yield the ratio of spinflip to non spinflip strength V_{0}τ/V_{τ}^{2} (1980AU02). Cross section measurements related to neutron production targets and detector efficiency calibration include (1987TE04, 1988HE08, 1989AM03, 1989BY02, 1989GU13, 1990BR24, 1990DR10, 1990TA11, 1992AM03, 1992DA20, 1997TA03, 1998KA20, 1998MA49, 1999BA73, 1999NA02, 1999NA15). Measurements or analyses of GamowTeller transition strength are reported in (1987TA13, 1989RA09, 1990RA08, 1994SA43). See also (1987HE22, 1987OR02). An analysis of neutron spectra for E_{p} = 120, 160 MeV and deduction of GamowTeller matrix elements are described in (2001GO25). A compilation of analyzingpower data is presented in (1987TA22). For studies of quadrupole excitation see (1994RA23, 1994WA22) and (1995YA12).

The 11MeV state has E_{x} = 11.01 ± 0.04 MeV, Γ = 298 ± 25 keV, J^{π} = 3/2^{}; T = 3/2 [the J^{π}; T assignments are based on the similarity of the angular distribution to that in the (p, ^{3}He) reaction to ^{7}Li*(11.13)]: see (1979AJ01).
Angular distributions have been studied for E_{p} = 2.8 to 7.0 MeV [see (1974AJ01)] and for 18 to 45 MeV (1986HA27; α_{0}, α_{1}, α_{2}; see for spectroscopic factors).

Angular distributions involving ^{7}Be*(0, 0.43) have been reported at E(^{3}He) = 25.5 to 70 MeV [see (1979AJ01, 1984AJ01)] and at E(^{3}He) = 33.4 MeV (1986CL1B; also A_{y}). See also (1986RA15) and see discussions of ^{12}C(^{3}He, ^{7}Be)^{8}Be [reaction 44] under ^{8}Be in (1988AJ01).
At E_{α} = 42 MeV, angular distributions have been measured involving ^{7}Be*(0, 0.43) and ^{9}Be_{g.s.}: see (1974AJ01). Angular distributions have also been measured at E_{α} = 49.0 and 80.1 MeV (1984GO03). An angular distribution and DWBA analysis for ^{12}C(α, ^{7}Be)^{9}Be is reported in (1991GL03).

Angular distributions have been reported at E(^{3}He) = 25.5 to 70 MeV to ^{7}Be*(0, 0.43) and to various states of ^{12}C: see ^{12}C in (1985AJ01). See also (1986BA89). A measurement of σ(θ) for ^{16}O(^{3}He, ^{7}Be)^{12}C at E(^{3}He) = 41 MeV is reported in (1987RA37). See also the calculation for E(^{3}He) = 60 MeV in (1995MA57).
Angular distributions have been studied at E(^{7}Li) = 50 MeV involving ^{7}Be*(0, 0.43) and various states of ^{16}N (1984CO20, 1986CL03). See also ^{16}N in (1986AJ04) and (1984BA53). A compilation and analysis of data for E(^{7}Li) = 78 MeV is presented in (1989GA26).
Target dependence of ^{7}Be production by bremmstrahlung photons (E_{γ} < 1200 MeV) incident on ^{27}Al and several other targets were studied by (2000MA75). See also (1998SH18).
See the calculations reported in (1986RA15). Measurements of σ(θ) for ^{24}Mg(^{3}He, ^{7}Be) at E(^{3}He) = 41 MeV are reported in (1987RA37). Spectroscopic factors were deduced (1988RA20).
Cross sections have been calculated for E(^{8}B) = 25.8, 415 MeV (1999SH20).
Production cross sections for ^{7}Be for protons with E_{p} = 0.66, 1.0 and 8.1 GeV incident on separated tin isotopes ^{112}Sn, ^{118}Sn, ^{120}Sn and ^{124}Sn were measured by an activation technique (1998DAZI).
