Distorted wave eikonal approximation calculation of elastic and inelastic differential cross sections in c.m. and lab frames for 40Ca nuclei

Abstract

Calculations have been made for elastic and inelastic differential cross sections of neutron scattering on nuclei near stability (N≥Z) such as 40Ca at energies 12,14,17 and 20MeV, at angles distributed between 20o and 180o. In this study, we applied Distorted Wave Eikonal Approximation for 40Ca nuclei using optical model of wood Saxon potential in two frames: center of mass and laboratory. Comparisons between the cross section estimated in the current work and the empirical data available demonstrate good approximation.
