Quantal description of nucleon exchange in a stochastic mean-field approach
Résumé
The nucleon exchange mechanism is investigated in central collisions of symmetric heavy ions in the basis of the stochastic mean-field approach. Quantal diffusion coefficients for nucleon exchange are calculated by including non-Markovian effects and shell structure. Variances of fragment mass distributions are calculated in central collisions of Ca40 + Ca40,Ca48 + Ca48, and Ni56 + Ni56 systems.
