Surveying the nucleon-nucleon momentum correlation function in the framework of quantum molecular dynamics model

Abstract

Momentum correlation functions of nucleon-nucleon pairs are presented for reactions with C isotopes bombarding a ${}^{12}C$ target within the framework of the isospin-dependent quantum molecular dynamics model. The binding-energy dependence of the momentum correlation functions is also explored, and other factors that have an influence on momentum correlation functions are investigated. These factors include momentum-dependent nuclear equations of state, in-medium nucleon-nucleon cross sections, impact parameters, total pair momenta, and beam energy. In particular, the rise and the fall of the strength of momentum correlation functions at lower relative momentum are shown with an increase in beam energy.
