Further investigation of 10,11B + 58Ni elastic scattering

Abstract

The recently measured 10,11B + 58Ni elastic scattering angular distributions are subjected to thorough analysis using different potentials such as optical and double folding, based on the CDM3Y6, with and without taking into account the effect of the rearrangement term, as well as the cluster folding potential. The cluster structure for 10B (11B) as composed of 6Li (7Li) core with an alpha particle orbiting this core is hence studied. The experimental data for the 10,11B + 58Ni nuclear systems are fairly reproduced with all the aforementioned potentials. The renormalization factors for the real double folded potential (N r ) indicate the need to reduce the strength of the produced potentials by ∼ 50% and ∼ 36% to reproduce the considered data for the 10B + 58Ni and the 11B + 58Ni nuclear systems, respectively. As a result of applying a rearrangement term to the double folding potential, a small change can be observed in the N r values. Cluster folding analysis for the 10B + 58Ni elastic scattering cross sections reveals a similar trend; the strength of the renormalization factor for the real part of the potential constructed based on the cluster folding model ( N RCF ) needs to be reduced by ∼ 48%. The observed reduction in the strength of the constructed double and cluster folding potentials reflects the weak binding nature of the 10B and 11B nuclei. It was somewhat surprising that the extracted N RCF = 1.24 ± 0.064 for the 11B + 58Ni system.
