摘　　要：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^(6.7)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^(6)Li+^(93)Nb and^(7)Li+^(115)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^(7)Li+^(181)Ta reaction by employing the extreme cluster model.
