Statistical simulation of the break-up of highly excited nuclei

We employ a model of multifragmentation of highly excited nuclei based on the statistical approach and a liquid-drop description of hot fragments. We consider the principal equations of this model and the methods of solving them in the canonical and macrocanonical approximations. We then calculate the multifragments break-up of nuclei taking into accont the de-excitation of hot fragments both by Fermi break-up and by evaporation of clusters. Finally, we analyze the main features of the multifragment break-up and compare them with those of the evaporation decay of highly excited nuclei. (orig.)
