A comprehensive theoretical analysis of ¹²B + ⁵⁸Ni elastic scattering measured for the first time by using different density distributions, different nuclear potentials and different cluster approaches

Recently, Zevallos et al [Phys. Rev. C 99, 064613 (2019)] measured, for the first time, the elastic scattering data of ¹²B+⁵⁸Ni reaction at ELab=30.0 and 33.0 MeV. For the first time, we show a comprehensive theoretical analysis of the experimental data of ¹²B+⁵⁸Ni reaction. First, we propose alternative density distributions for the ¹²B nucleus, and obtain the elastic scattering angular distributions of ¹²B+⁵⁸Ni reaction with the help of these densities. Secondly, we calculate the elastic scattering cross-sections of ¹²B+⁵⁸Ni reaction by using 13 different nuclear potentials to reveal alternative nuclear potentials. Finally, we examine cluster structures such as α+⁸Li and n+¹¹B of the ¹²B nucleus by using a simple approach, and acquire elastic scattering cross-sections of ¹²B+⁵⁸Ni reaction over these cluster approaches. We compare all the theoretical results with the experimental data, and discuss their similarities and differences. Also, we propose new equations of both normalisation constant and imaginary potential parameters for all the systems analysed. (author)
