New empirical formulae for the in-medium nucleon-nucleon cross-section

摘要

New empirical formulae for in-medium nucleon-nucleon cross-section are presented and used to study the proton-nucleus interaction in the framework of Glauber model. The total, absorption and elastic cross-sections are calculated for many target nuclei. The calculated total cross-sections using the in-medium effective factor, f(m4), give a reasonable fit with the experimental data. In addition, the in-medium factors f(m1), f(m2) and f(m3) successfully reproduce the absorption cross-section at energies up to 600 MeV. (C) 2019 Published by Elsevier B.V.
