Finite Range Effects of Local Interactionin Intermediate Energy HIC

  • A finite range Gaussian 2-body interaction is applied in stead of the zero range 2-body part of the Skyrme interaction in the isospin-dependent quantum molecular dynamics model to simulate the transverse momentum in the reaction of system 93Nb(E=400MeV/u, b=3fm)+93Nb. The results show 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.

Abstract: A finite range Gaussian 2-body interaction is applied in stead of the zero range 2-body part of the Skyrme interaction in the isospin-dependent quantum molecular dynamics model to simulate the transverse momentum in the reaction of system 93Nb(E=400MeV/u, b=3fm)+93Nb. The results show 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.
