Nucleon transfer contribution to the absorptive potential in heavy-ion scattering

Abstract

We propose a simple model for estimating the nucleon transfer contribution to the imaginary part of the nucleus-nucleus optical potential. Using the proximity method we calculate the transfer probability per unit time in terms of the flux of nucleons between two slabs. Pauli blocking and barrier penetration effects are taken into account. We compare our results with phenomenological potentials at the strong absorption radius.
