Entrance channel dynamics in 40Ca+40Ca at 35A MeV

Abstract The entrance channel dynamics of the 40 Ca+ 40 Ca reaction at 35A MeV is modeled with the recently developed QMD codes, EQMD and AMD-V. Drastic differences are observed in the entrance channel dynamics calculated by the two models. AMD-V with a Gogny force reproduces the experimental results over all. The importance of the introduction of the diffusion process to the centroid motion of wave packets is suggested.
