Fusion-Fragmentation Model and ALADIN Multifragmentation Data

  • The fusion-fragmentation model is used to analysis the ALADIN data of the multifragmentation of projectile remnant in reaction of 600 MeV/u Au bombarding Cu target. Since the fusion-fragmentation model includes both the dynamical formation and the statistical disassembly of hot nucleus, all the ALADIN data can be reproduced very well if the model parameter concerning excitation energy is somewhat adjusted.

Abstract: The fusion-fragmentation model is used to analysis the ALADIN data of the multifragmentation of projectile remnant in reaction of 600 MeV/u Au bombarding Cu target. Since the fusion-fragmentation model includes both the dynamical formation and the statistical disassembly of hot nucleus, all the ALADIN data can be reproduced very well if the model parameter concerning excitation energy is somewhat adjusted.
