Effect of neighbouring fragments on sequential binary decay

The effective fission barrier of a hot nucleus in nuclear multifragmentation in the sequential binary decay model depends on the configuration of the neighbouring fragments generated in the previous stages of binary decay. Taking this into consideration, various observables related to multifragmentation in intermediate energy nuclear collisions are evaluated in the transition state model. The effect of recombination of the fragments during dynamical evolution of the system is also taken into account. The results of our calculations are confronted with the experimental data from fragmentation in the reaction Au on Cu at 600 MeV/nucleon bombarding energy. (orig.)
