Finite range effects of nuclear force in intermediate energy heavy ion collisions
Lie-Wen Chen, Feng-Shou Zhang, Wen-Fei Li
Abstract
Within the framework of an isospin-dependent quantum molecular dynamics model, the zero-range 2-body part of the Skyrme interaction is replaced by a finite-range Gaussian 2-body interaction. From the transverse momentum analysis in the reaction of system 93Nb + 93Nb at energy of 400 MeV/nucleon and impact parameter b=3 fm, it is shown that the finite-range nuclear force enhances the transverse momentum of the reaction system and it can partly replace the momentum dependent part of the nucleon-nucleon interaction.
