Effects of the entrance channel mass asymmetry in fusion reactions

  • The symmetric and asymmetric fusion reaction systems forming the same compound nuclei 26Al, 30Si, 38Ar and 170Hf are investigated with the frame of improved isospin dependent quantum molecular dynamics model. The entrance channel mass asymmetry dependence of compound nucleus formation is found by analyzing the shell correction energies, the Coulomb barriers and the fusion cross sections. The calculated fusion cross sections agree quantitatively with the experimental data. The results indicate that compound nucleus formation is favorable for the systems with larger mass asymmetry because of the smaller Coulomb contribution to the fusion barrier.

Effects of the entrance channel mass asymmetry in fusion reactions

    Corresponding author: ZHANG Feng-Shou,

Abstract: 

The symmetric and asymmetric fusion reaction systems forming the same compound nuclei 26Al, 30Si, 38Ar and 170Hf are investigated with the frame of improved isospin dependent quantum molecular dynamics model. The entrance channel mass asymmetry dependence of compound nucleus formation is found by analyzing the shell correction energies, the Coulomb barriers and the fusion cross sections. The calculated fusion cross sections agree quantitatively with the experimental data. The results indicate that compound nucleus formation is favorable for the systems with larger mass asymmetry because of the smaller Coulomb contribution to the fusion barrier.
