Elastic and Inelastic Scattering of 9,10,11Be by 64Zn and 120Sn Nuclei at Different Energies

In the context of the double folding optical model, the elastic and inelastic scattering of 9Be + 120Sn at Elab (9Be) = 31, 42 and 50 MeV and 9,10,11Be + 64Zn elastic scattering at Ec.m. = 24.5 MeV are investigated. Real folded potentials are generated using the DDM3Y interaction based on the suggested density distributions for the 9,10,11Be nuclei. The imaginary potential is taken in the traditional standard Woods–Saxon form. Coupled channel (CC) calculations using a rotational model are performed for 9Be inelastically scattered from 120Sn, leading to different 120Sn excited states. Successful reproduction of the observed angular distributions of the elastic and inelastic scattering differential cross-sections has been achieved using the derived potentials. Special attention is paid to the previously suggested ( $$ {3}_1^{-} $$ , Ex = 2.40 MeV) 120Sn excited state in order to present the contributions come from - $$ {3}_1^{-} $$ at 2.40030(5) MeV, $$ {2}_3^{+} $$ at 2.42090(3) MeV, $$ {2}_2^{+} $$ at 2.355383(24) MeV, and $$ {4}_1^{+} $$ at 2.465632(23) MeV—in forming the inelastic data observed at Ex = 2.41 MeV.
