Quantal description of nucleon exchange in a stochastic mean-field approach
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. © 2015 American Physical Society.
