Multi-Nucleon Transfer in Central Collisions of ${}^{238}$U + ${}^{238}$U

Abstract

Quantal diffusion mechanism of nucleon exchange is studied in the central collisions of ${}^{238}$U + ${}^{238}$U in the framework of the stochastic mean-field (SMF) approach. For bombarding energies considered in this work, the di-nuclear structure is maintained during the collision. Hence, it is possible to describe nucleon exchange as a diffusion process for mass and charge asymmetry. Quantal neutron and proton diffusion coefficients, including memory effects, are extracted from the SMF approach and the primary fragment distributions are calculated.
