Disassembly of an excited nuclear aggregate through sequential decay

Abstract

The disassembly of an excited nuclear aggregate is described as a time-dependent decay process in which clusters are continuously and sequentially emitted by the primitive aggregate and those which have already been formed at a given time. The dynamics describe the rate at which the different species are generated as well as the rate at which the system de-excites and expands isotropically in space. The model is applied to the study of sequentially decaying40Ar as a function of the initial excitation energy.
