Abstract

Optical model analysis of the elastic scattering analysis of α + 40Ca at Elab=104 and 141.7 MeV have been performed using the folding model approach of the nuclear reaction video (NRV) knowledge base code. The M3Y-type effective nucleon-nucleon interaction derived using the lowest order constrained variational (LOCV) approach for mass number A=40 was used to obtain the results. Elastic scattering differential cross section data were obtained for this system at two bombarding energies. The calculated differential cross sections are in good agreement with the experimental results and the anticipated mass dependence of the M3Y-type effective interaction improved the results at forward angles. This shows that, the mass dependence of the M3Y-type effective interaction in our results should be of value in the description of the scattering of other nuclear systems
