Abstract
The recently measured B-10,B-11 + Ni-58 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 B-10 (B-11) as composed of Li-6 (Li-7) core with an alpha particle orbiting this core is hence studied. The experimental data for the B-10,B-11 + Ni-58 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 similar to 50% and similar to 36% to reproduce the considered data for the B-10 + Ni-58 and the B-11 + Ni-58 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 B-10 + Ni-58 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 similar to 48%. The observed reduction in the strength of the constructed double and cluster folding potentials reflects the weak binding nature of the B-10 and B-11 nuclei. It was somewhat surprising that the extracted N ( RCF ) = 1.24 +/- 0.064 for the B-11 + Ni-58 system.
