Effect of shell structure on the nucleon transfer contribution to the imaginary part of the heavy ion optical potential.

Abstract

We calculate the imaginary part of the heavy ion optical potential at the strong absorption radius assuming that the absorption is essentially given by the depopulation of the entrance channel due to nucleon transfer. The transfer probabilities of individual nucleons between specific quantum states are calculated with a simple formula. The method is applied to several pairs of nuclei and the results are compared to the experiment and other previous calculations.
