Dynamics Study on the Intermediate Energy Heavy Ion Collisions

Abstract：

The collision dynamic and the multifragmentation mechanism of the intermediate energy heavy ion have been studied by means of improved quantum molecular dynamics (IQMD) via studying dynamical observables which identify dynamical properties of the intermediate energy heavy ion collisions, such as the time development of the transverse momentum, collision number, density of nuclear matter and thermalization. At the same time, the dynamical ingredients governing the collision dynamics of heavy ion collisions, such as the equation of state, momentum dependent interaction and medium effect, have been analyzed and discussed.
