Neutron pair transfer in sub-barrier capture process

Abstract

The sub-barrier capture reactions following the neutron pair transfer are proposed to be used for the indirect study of neutron-neutron correlation in the surface region of nucleus. The strong effect of the dineutron-like clusters transfer stemming from the surface of magic and non-magic nuclei ${}^{18}$O, ${}^{48}$Ca, ${}^{64}$Ni, ${}^{94,96}$Mo, ${}^{100,102,104}$Ru, ${}^{104,106,108}$Pd, and ${}^{112,114,116,118,120,124,132}$Sn is demonstrated. The dominance of two-neutron transfer channel at the vicinity of the Coulomb barrier is further supported by time-dependent mean-field approaches.
