Abstract

For the measured elastic scattering angular distribution of the tightly bound ¹⁰B on the ⁵⁸Ni target, at energies close to the Coulomb barrier, the study is made to extract the total reaction cross-section. Total reaction cross-sections were extracted from the elastic-scattering analysis using the optical model with double-folding–type potentials. We have also taken the total reaction cross-section of the systems with the same mass range target, that is, ⁵⁸Ni and different projectiles, from the literature and tried to compare them with our system by reducing the cross-sections, for the elimination of trivial effects due to different sizes and different Coulomb barriers. In addition to that, for all the considered systems, one-channel calculations that account only for fusion have been performed to study the quantitative effect of the direct reaction channels on the total reaction cross-section.
