Abstract：
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 turns 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.
