Effect of N,Z Dependent Macroscopic Potential to cluster Formation in Quantum Molecular Dynamics

  • Based on the QMD model, in addition to the Skyrme-type, Yukawa and Coulomb interactions, a macroscopic potential, which is dependent on the neutron andproton number N,Z of the cluster and consists of the symmetrical energy of liquiddrop model and shell and pairing correction energies, has been taken into account.It improved the reasonable structure of the cluster formation in heavy ion reactionswith intermediate energy.

Abstract: Based on the QMD model, in addition to the Skyrme-type, Yukawa and Coulomb interactions, a macroscopic potential, which is dependent on the neutron andproton number N,Z of the cluster and consists of the symmetrical energy of liquiddrop model and shell and pairing correction energies, has been taken into account.It improved the reasonable structure of the cluster formation in heavy ion reactionswith intermediate energy.
