초록
We study the onset of nuclear vaporiza- tion in the reactions of 16O+80Br within the frame- work of QuantumMolecular Dynamics (QMD) model. The clusterization algorithmMinimum Spanning Tree (MST) is used to identify the fragment structures. The mean charge in each event is correlated and plotted against incident energy of the projectile to find out the energy of the onset of vaporization. We find QMD+MST is able to reproduce the ex- perimental results of the average charge per event qualitatively at all incident energies, whereas quan- titative behavior can be reproduced only above 50 MeV/nucleon energy. We also varied the spatial dis- tance constraint in MST method to see its effect on the onset of vaporization.
Abstract
We study the onset of nuclear vaporiza- tion in the reactions of 16O+80Br within the frame- work of QuantumMolecular Dynamics (QMD) model. The clusterization algorithmMinimum Spanning Tree (MST) is used to identify the fragment structures. The mean charge in each event is correlated and plotted against incident energy of the projectile to find out the energy of the onset of vaporization. We find QMD+MST is able to reproduce the ex- perimental results of the average charge per event qualitatively at all incident energies, whereas quan- titative behavior can be reproduced only above 50 MeV/nucleon energy. We also varied the spatial dis- tance constraint in MST method to see its effect on the onset of vaporization.
