Contribution of different components of interaction potential towards global nuclear stopping

Abstract

We present our analysis of the effect of isospin content as well as the contributions of various components of nucleon–nucleon interaction potential on stopping ratio of protons and neutrons for the reaction \(^{120}_{50}\hbox {Sn}+{}^{120}_{50}\hbox {Sn}\). This study is performed within the framework of isospin-dependent quantum molecular dynamics model. We show that the momentum-dependent interactions affect the nuclear stopping to a larger extent compared to the other components of the nucleon–nucleon interaction potential. The isospin-dependent nucleon–nucleon cross section is also found to affect the stopping in central collisions only.
