THE ORIENTATIONAL-AVERAGE EFFECTS OF HEAVY-ION COLLISIONS INDUCED BY DEFORMED NUCLEI AT INTERMEDIATE ENERGY

The deformed projectiles and targets are expected to play different roles in heavy-ion collisions (HICs) at intermediate energy compared with spherical ones. With an isospin dependent quantum molecular dynamics (IDQMD) model, in despite of averaging all the orientations of axisymmetric deformed 24Mg + 24Mg collisions, it is still found that NN collision number, nuclear stopping power (R) and multiplicity of fragments have considerable differences compared with spherical 24Mg + 24Mg collisions.
