“…The analyses by Reber et al [26,27] of polarized Li scattering by ' C at 30 MeV found that reorientation of the ground state of Li was a major contribution to the elastic scattering TAP T2&. A similar conclusion has also been reported by Kerr et al [28].…”

Recently published data for the elastic scattering of 70.5 MeV polarized Li by Ni have been compared with the results of coupled-channels calculations. The diagonal and off-diagonal potentials used in the analysis were generated from phenomenological u + Ni and d + Ni optical potentials via the cluster-folding method. Examined were the effects of projectile excitation to the three low-lying T=0 resonant states and to nonresonant continuum states in the energy range 0.63 MeV -10.03 MeV, relative to the Li~o. +d breakup threshold at 1.47 MeV. In common with earlier analyses, calculations limited to the resonant excited states reproduced the data only when the interaction and coupling potentials were renormalized. However, the inclusion of the nonresonant excited states removed the need for this renormalization. Calculations including both the resonant and nonresonant states yielded a description of the differential cross section data superior to that resulting from calculations limited to the resonant states even when the latter were performed with renormalized potentials. Calculations of the tensor analyzing powers reproduced the data well and favored a near zero value for the spectroscopic amplitude of the D-state admixture in the Li ground state cluster wave function.PACS number(s): 25. 10.s, 24. 10.Eq, 24.70.+s

“…An earlier analysis of the full set of analyzing powers taken previously at 30 MeV showed that the smaller angle vector AP arose from J-dependent absorptive effects, while the larger angle vector AP arose from the presence of an explicit spin-orbit interaction [8]. The presence of a tensor interaction manifested itself in a nonzero T2&.…”

“…Li elastic scattering analyzing powers have been measured, they too have been found to have surprisingly large values, especially Tzt [5,8]. To date, only two complete sets of Li analyzing powers exist at bombarding energies substantially over the Coulomb barrier, and no complete set exists at two widely separated energies for the same target.…”

A complete set of analyzing powers (iT», Tzo, Tz, , and Tzz) are reported for the elastic scattering of 50 MeV Li by ' C. They are as large as or larger than those measured earlier for 30 MeV Li. A combined optical model analysis of both energies shows Tz& to arise from the tensor interaction, Tzo to involve a combination of tensor and J-dependent interactions, and iT» to be the most complicated, arising from an explicit spin-orbit, as well as tensor and J-dependent interactions. A coordinate transformation of the data and calculations, suggested in the earlier work of Hooton and Johnson, provides the clearest evidence for the need of a tensor interaction to describe Li scattering. Examining the optical model calculations in terms of transferred angular momentum amplitudes provides further insight into the role played by each interaction. Also presented are the analyzing powers for the "He( Li, He) polarimeter reaction at this higher bombarding energy.PACS number(s): 24.70.+s, 24. 10.Ht, 25.70.Bc, 21.30.+y

“…This enhancement has been attributed to either single nucleon, or cluster transfer, in cases where the difference between the projectile and target mass equals the mass of the required transferred particle. For example, 9 Be ϩ 12 C elastic scattering ͓3͔ has a significant contribution from 3 He transfer at large angles. For the case of 6 Li ϩ 12 C, not only does the elastic scattering have a larger than expected cross section at large angles, but so does the scattering to either 6 Li͑2.18 MeV͒ ϩ 12 C͑g.s.͒ or 6 Li͑g.s.͒ ϩ 12 C͑4.44 MeV͒.…”

Statistical compound-nucleus contributions to enhanced back-angle cross sections for 6 Li ϩ 12 C elastic scattering and for inelastic scattering to the channels, 6 Li͑3 ϩ , 2.18 MeV͒ ϩ 12 C͑g.s.͒ and 6 Li͑g.s.͒ ϩ 12 C͑2 ϩ , 4.44 MeV͒, are studied. Differential cross sections and vector analyzing powers in the range ⌰ c.m. Ϸ130°-165°have been measured at E c.m. ϭ 20 MeV by detecting recoil 12 C nuclei from 6 Li ជ elastic scattering and inelastic scattering to the 6 Li͑3 ϩ , 2.18 MeV͒ state. Adding a statistical compound-nucleus contribution is shown in general to reduce the magnitude, and to leave unaffected the sign, of theoretical calculations of vector analyzing powers. Analysis, including Hauser-Feshbach calculations, of the above data along with previous data indicates that compound-nucleus contributions are unimportant in the elastic and inelastic 6 Li͑2.18 MeV͒ scattering channels, and are insufficient to resolve discrepancies between current coupled-channels calculations and large-angle data for inelastic 12 C͑4.44 MeV͒ scattering.
