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.

C.B. would like to thank the C.N.R. (Italy) for a grant which allowed him to stay at the Département de Physique Théorique, C.R.N., Strasbourg and the colleagues of the Theory Group for their hospitality. One of us (J.R.) acknowledges a very interesting and fruitful discussion with J. Hüfner about the model and the results.
