采用同位旋相关的量子分子动力学模型研究了中能重离子碰撞中核阻止本领Qzz/A和R对系统大小、初始N/Z比、同位旋对称势以及两体散射截面的介质修正等的依赖关系。研究表明,初始N/Z和同位旋对称势对阻止本领的影响很弱,Qzz/A和R的激发函数依赖于两体散射截面的介质修正和核物质状态方程。我们的研究指出,Qzz/A和R的激发函数能提供关于两
The isospin-dependent quantum molecular dynamics model has been used to study the dependence of Qmax / A and R on the system size, initial N / Z ratio, isospin symmetry and medium correction for two-body scattering cross section in heavy ion collisions relationship. The results show that the initial N / Z and isospin symmetry have a weak influence on the stopping ability, and the excitation function of Qzz / A and R depends on the medium correction and the nuclear matter equation of state of the two-body scattering cross section. Our research shows that the excitation functions of Qzz / A and R can provide information about two
