A study about the 12C(18O, 16O) 14C two-neutron transfer reaction was performed at the Catania INFN-LNS laboratory at 84 MeV incident energy. The 16O ejectiles produced in the reactions were momentum analyzed and identified by the MAGNEX spectrometer. The Q-value spectrum of 14C shows several known bound and resonant states, in particular states with 2p-4h configuration respect to the 16O core. The integrated cross sections show an enhanced yield for the two-neutron transfer compared to the one-neutron transfer. These results are some experimental evidences that the (18O, 16O) reaction proceeds mainly by the direct transfer of the neutron pair, instead of a second order process.

Abstract

A study about the 12C(18O, 16O) 14C two-neutron transfer reaction was performed at the Catania INFN-LNS laboratory at 84 MeV incident energy. The 16O ejectiles produced in the reactions were momentum analyzed and identified by the MAGNEX spectrometer. The Q-value spectrum of 14C shows several known bound and resonant states, in particular states with 2p-4h configuration respect to the 16O core. The integrated cross sections show an enhanced yield for the two-neutron transfer compared to the one-neutron transfer. These results are some experimental evidences that the (18O, 16O) reaction proceeds mainly by the direct transfer of the neutron pair, instead of a second order process.
