AN INVESTIGATION OF α-PARTICLES ELASTIC SCATTERING ON 24Mg AND 28Si BY USING CLUSTER FOLDING MODEL

Abstract

Using the α-like cluster and uncluster nucleonic structure of 24 Mg and 28 Si nuclei, α-nucleus single-folding cluster optical potentials have been generated based upon effective α–α and α-nucleon (N) interactions. Angular distributions of the differential cross-section of α elastic scattering by 24 Mg , and 28 Si nuclei have been analyzed over a wide range of incident energies, Eα = 21.9-175.5 MeV , where anomaly in large angle scattering and rainbow scattering features have been investigated. We successfully reproduce the elastic scattering differential cross-section for energy range Eα = 22.2-172.5 MeV for 24 Mg target and 21.9-166 MeV for 28 Si target without renormalization except a few cases at low energies. The energy dependence of the extracted real and imaginary volume integrals and total reaction cross-section has been investigated.
