“…26) Moreover, in a single folding model, the SBM interaction explains the p + 6 Li elastic and inelastic scattering data over an energy range of 10 to 136 MeV. 22) It was also found to facilitate solution of the analyzing power puzzle for the same reaction in the above stated energy range. In view of its success with the stable but loosely bound nucleus 6 Li, the same model is used in the present work for the reanalysis of the 68A MeV p + 11 Li scattering data of RIKEN.…”

The 68A MeV 11 Li + p scattering data are reanalysed in a microscopic framework. The real, imaginary and transition potentials are constructed in a single folding model using an isospin, density and momentum dependent finite-range effective nucleon-nucleon interaction and several microscopic 11 Li density distribution prescriptions for 11 Li. The transition density is formulated in a soft-dipole resonance mode (SDR) by modifying the Goldhaber-Teller (G-T) model. Analyses of the angular distribution of the 1.3 MeV excited state gives a result consistent with SDR excitation in 11 Li with significant channel coupling effect. at UNIVERSITY OF PITTSBURGH on July 25, 2015 http://ptp.oxfordjournals.org/ Downloaded from at UNIVERSITY OF PITTSBURGH on July 25, 2015 http://ptp.oxfordjournals.org/ Downloaded from

“…The values of parameters n, C l , C u , a, b, d are given in Table 1. These constants are found to reproduce the bulk properties of nuclear matter and of finite nuclei [11,12] and are known also to explain the p + 4,6,8 He, 6,7,9,11 Li scattering data successfully [2,4,[13][14][15][16]. The parameters are determined without exchange effects and thus they contain the effect indirectly though in a very approximate way.…”

The elastic and inelastic scattering of protons from mirror nuclei 18 Ne and 18 O are studied in a folding model approach. For comparison, two different effective interactions are folded with Hartree-Fock densities to obtain the nuclear interaction potentials. Both of them provide equivalent descriptions to the data and the deformation parameters extracted from inelastic scattering are reasonable. The density dependence parameters obtained from nuclear matter calculations and used for present analysis also provide a good estimate for the nuclear mean free path. The present formalism unifies radioactivity, nuclear matter and nuclear scattering.

The proton-inelastic scattering from 6,8 He and 7,11 Li nuclei are studied in a folding model approach. A finite-range, momentum, density and isospin dependent nucleon-nucleon interaction (SBM) is folded with realistic density distributions of the above nuclei. The renormalization factors N R and N I on the real and volume imaginary part of the folded potentials are obtained by analyzing the respective elastic scattering data and kept unaltered for the inelastic analysis at the same energy. The form factors are generated by taking derivatives of the folded potentials and therefore required renormalizations. The β values are extracted by fitting the p + 6,8 He, 7,11 Li inelastic angular distributions. The present analysis of p + 8 He inelastic scattering to the 3.57 MeV excited state, including unpublished forward angle data (RIKEN) confirms L = 2 transition. Similar analysis of the p + 6 He inelastic scattering angular distribution leading to the 1.8 MeV (L = 2) excited state fails to satisfactorily reproduce the data.
