Global phenomenological optical model potential for 14N-nucleus elastic scattering

Abstract

In this paper, a set of global optical model potential parameters of [Formula: see text]N is obtained by fitting the experimental data of the elastic scattering angular distributions for the targets from [Formula: see text]Mg to [Formula: see text]Pb below 200 MeV. The global optical model potential parameters of [Formula: see text]N-nucleus reactions obtained are analyzed and used to describe the experimental data. It is found that the present form of the global optical model potential could reproduce the experimental data. Moreover, the elastic scattering angular distributions for the reactions of [Formula: see text]N inducing on some lighter targets and the elastic scattering observable quantity for the reactions involving [Formula: see text]N projectile are predicted using the obtained global optical model potential, and a reasonable description of the experimental data is obtained by comparing with the existing corresponding experimental data.
