Coupled channel analysis of neutron transfer in ^6,7Li induced reactions around the Coulomb barrier*

Abstract The coupled reaction channel approach has proven to be quite effective in explaining the mechanism of nucleon transfer in heavy-ion reactions. Nevertheless, significant ambiguities remain regarding the selection of potential parameters and the states of the nuclei that should be coupled together for a specific reaction channel. In this study, the excitation functions for one- and two-neutron transfer in Li-induced reactions on various targets were analyzed using the coupled reaction channel formalism. Spectroscopic amplitudes were taken from the existing literature and shell model calculations. The one-neutron transfer cross sections from Li+ Nb and Li+ In reactions were reasonably well reproduced by coupled reaction channel calculations. A reasonable match for the measured cross sections was also obtained for the two-neutron transfer in the Li+ Ta reaction by employing the extreme cluster model.
