TOTAL REACTION CROSS SECTIONS FOR 100-MeV ALPHA PARTICLES USING SEMI-PENOMENOLOGICAL NUCLEON DENSITY DISTRIBUTION

Abstract

Theoretical study of α total reaction cross-sections for 50 Ti , 52 Cr , 54,58 Fe , and 58,64 Ni nuclei at 100 MeV is presented. Working within the framework of Coulomb modified Glauber model, we calculate α reaction cross-sections in terms of the phenomenological N-α amplitude using the semi-phenomenological nucleon density distribution proposed by Gambhir and Patil [Z. Phys.A324 (1986) 9]. We find that the semi-phenomenological density reproduces the observed behaviour of the reaction cross-sections for the isotopes and isotones quite satisfactorily.
