Abstract

The structure effects of project and target in heavy ion collision at low energy is more important compared with the effects at high energy, which requires the transport model to describe the ground properties of nuclei more reasonably. In this paper, we carry out calculations of the ground state properties, such as binding energy and root mean square radius, of different isotope chains from light to heavy mass region by an extended quantum molecular dynamics (EQMD) model and compare the results with data. It is found that the EQMD model not only can reproduce ground state properties of stable nuclei very well, but also can reasonably describe the ground state binding energy of nuclei far from βstability line. Compared with other versions of QMD, EQMD model greatly improves the description of the stability of initialized nuclei. Recent investigations would serve as a starting basis for studying the reaction mechanisms of elastic scattering, fusion, transfer and breakup induced by weakly bound nuclei by the microscopic dynamical model.
