Microscopic analysis of the ⁸B + ⁵⁸Ni elastic scattering at energies from 20.7 to 29.3 MeV

The elastic scattering differential cross sections for ⁸B + ⁵⁸Ni at energies 20.7, 23.4, 25.3, 27.2, and 29.3 MeV are analyzed within the framework of the optical double folding potential. The density and energy-dependent CDM3Y6 effective nucleon-nucleon interaction and the Sao-Paulo potential have been used to generate the microscopic and semi-microscopic optical potentials. The cluster form in addition to three other density distributions for the ⁸B nucleus is explored. The results of the Sao-Paulo potentials are more appropriate to reproduce the five sets of data than CDM3Y6. The real and imaginary volume integrals with the reaction cross section are discussed in comparison with the previous studies. (author)
