Understanding reaction mechanisms of multi-nucleon transfer reactions in deformed nuclei

In our recent study, we have investigated reaction mechanism aspects of multi - nucleon (up to nine nucleons) transfer reactions at near and above Coulomb barrier energies on various target nuclei. The data f or ¹⁸O+²⁰⁶Pb were analyzed in a fully microscopic framework of the Time-Dependent Hartree-Fock (TDHF) theory and a reasonably good agreement with the measurement for transfer of a few nucleons was obtained. However, the TDHF calculations become less accurate as the number of nucleons transferred increases. Inclusion of effects of particle evaporation on the cross sections gives some improvement towards the measurement, however, the calculations still underestimate the measured cross sections by a significant amount especially for the cases where a large number of nucleon transfer are involved. In order to have a further understanding on these aspects, recently we have measured multi-nucleon transfer cross sections on deformed nucleus ¹⁵⁴Sm (prolate shape, β = 0.32)
