The elastic scattering data of 10 B+ 120 Sn at 31.5, 33.5, 35, 37.5, and 39.7 MeV incident energies are reanalyzed using the São Paulo Potential version 2 (SPP2) and the Brazilian Nuclear Potential (BNP) in the framework of optical-model-based double folding (DF) model. The optical potential and the elastic scattering cross sections are obtained using two forms of matter densities for 10 B: the experimental density which is twice the charge density (CD) and theoretical density calculated through the Dirac-Hartree-Bogoliubov (DHB) model. The real part of the optical potential is considered in a microscopic form, while the imaginary part in both microscopic and phenomenological forms. The sensitivity of the elastic scattering cross sections to the two potentials and the two forms of projectile densities is examined. The SPP2 with CD density for the projectile performs better than the BNP as it requires renormalization factors of N R = 1.0 and N I ∼ 0.7 - 1 for the real and imaginary potentials, respectively. This is also better than previous calculations using the first version of SPP which requires N I = 0.25 - 0.35 to describe the 10 B+ 120 Sn elastic scattering data. In general, the theoretical calculations show good agreement with the experimental data. [ABSTRACT FROM AUTHOR] |
