NUCLEAR STOPPING AND EQUATION OF STATE

摘要：

With the help of an updated transport model — ultrarelativistic quantum molecular dynamics, the nuclear stopping quantity vartl is used to investigate the stiffness of the equation of state of the nuclear matter as well as medium modifications of nucleonnucleon elastic cross sections in heavy ion collisions (HICs) at SIS energies. It is found that the excitation function of the vartl value is sensitive to both the mean field and the two-body scattering. Hence, both parts should be taken into account consistently. At low SIS energies, in order to describe the FOPI data, the density dependence of the cross sections should be stronger implying that the effect of the nuclear structure may be noticed in the process of the HICs.
