  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.
