Résumé |
In the first part of the talk, we provide a brief description of Stochastic Mean-Field Approach for describing heavy-ion dynamics at low energies [1]. The approach gives rise to a quantal diffusion mechanism for multi-nucleon exchange in the di-nuclear regime of heavy-ion collisions near barrier energies. Some examples of calculations of the primary fragment mass and charge distributions are presented in collisions of 40,48Ca + 238U and 238U + 238U systems [2]. We also discuss some aspects of the recent calculations performed for the spinodal instabilities in nuclear matter and for the spontaneous fission of 258Fm by employing the Stochastic Mean-Field Approach [3].
