Recently, Zevallos et al [ Phys. Rev. C 99 , 064613 (2019)] measured, for the first time, the elastic scattering data of 12 B + 58 Ni reaction at E Lab = 30.0 and 33.0 MeV. For the first time, we show a comprehensive theoretical analysis of the experimental data of 12 B + 58 Ni reaction. First, we propose alternative density distributions for the 12 B nucleus, and obtain the elastic scattering angular distributions of 12 B + 58 Ni reaction with the help of these densities. Secondly, we calculate the elastic scattering cross-sections of 12 B + 58 Ni reaction by using 13 different nuclear potentials to reveal alternative nuclear potentials. Finally, we examine cluster structures such as α + 8 Li and n + 11 B of the 12 B nucleus by using a simple approach, and acquire elastic scattering cross-sections of 12 B + 58 Ni 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.
