Modified-Mcintyre-Model Analysis of Heavy-Ion Elastic Scattering at Medium Energies

Abstract

The Aj function of the Mclntyre model was modified to fit the measured differential cross section of the elastic scattering 14 N on 12 C at £ kb = 22.5 MeV, which shows extensive structure for large cm.-system angles. The modified Aj function is a Woods-Saxon type function with a sharp drop for a certain I value. This drop simulates a great number of surface reactions, which diminish the elastic channel in the case of grazing collision.
