Analysis of the dependence of the few-neutron transfer probability on theQ-value magnitudes

Abstract

Employing the known experimental fact that the sub-barrier capture (fusion) enhancement in the reactions $^{40}\mathrm{Ca}+^{94,96}\mathrm{Zr}$ and $^{40}\mathrm{Ca}+^{116,124,132}\mathrm{Sn}$ is not proportional to the magnitudes of $Q$ values for the neutron transfer, the similarity of the structure of the target nuclei, and the conservation of the total reaction flux, we analyze the dependence of a few-neutron transfer probability on the magnitudes of $Q$ values. This analysis is checked by the calculations of nucleon transfer probabilities within the time-dependent Hartree-Fock plus BCS approach.
