Dynamical decay of nuclei at high temperature: Competition between particle emission and fission decay

  • Nuclei
  • Published:
Zeitschrift für Physik A Atomic Nuclei

Abstract

A generalized diffusion equation is propounded to follow the time evolution of an excited nucleus towards fission including along the particle decay. This theoretical model is built in order to try to analyse the anomalous behaviour of particle emission observed in many experimental data for heavy-ion induced reactions. Some calculations for the systems194Hg,170Yb and248Cf are presented. A possible extension of this generalized formalism is suggested to deal more consistently with the experimental data.
