利用改进的量子分子动力学研究了16O+16O库仑位垒附近的熔合反应,用连接函数的方法对体系的表面能做了改进.利用这种方法避免了非物理的核子发射,熔合截面有了明显的增加,这是因为体系的表面形变效应可以通过连接函数来体现,从而抑制了弹靶在熔合过程中非物理的核子发射.

By using an improved isospin dependent quantum molecular dynamics model, the fusion reaction near coulomb barrier is studied for the 16O + 16O system. The surface energy of the system is improved by a switch function method, which combines the surface energies of projectile and target with the one of compound nucleus in a proper way. The calculated fusion cross section increases obviously by using this method, which tums away the unphysical nucleon emission in the process of projectile and target approaching since the deformation effect of the surface has been embodied by the switch function method.
