Abstract
In this study, the available Li-6 + Ni-58 angular distributions in the energy range 9.9-600 MeV are reanalyzed theoretically within the framework of various interaction potentials based on both phenomenological and microscopic approaches. The well-known cluster structure of Li-6 as a core of alpha-particle and a deuteron revolving around this core was observed and considered for generating the Li-6 + Ni-58 cluster folding potential. At all energies, the analyses performed within the framework of the considered potentials gave reasonable fits of data. The performed cluster folding analysis showed the necessity to reduce the potential's strength by similar to 50-53% for describing the data fairly. The observed reduction in the strength of microscopic potential is mainly due to the dissociation of Li-6 in the field of the target nucleus and consequently the high Li-6 clusterization probability. The data has been also successfully reanalyzed using unrenormalized real Sao Paulo potential.
