Beyond the neutron-drip line: two-neutron decay of unbound nuclei

Nuclear Theory 2019-01-30 v1 Nuclear Experiment

Abstract

We discuss a decay of unbound nuclei beyond the neutron drip-line using a three-body model with a core nucleus and two valence neutrons. We particularly discuss the role of dineutron correlation between the valence neutrons in the two-neutron emission from the ground state of 26^{26}O and 10^{10}He nuclei. Our calculations clearly indicate that the emission of the two neutrons in the back-to-back direction is enhanced due to the dineutron correlation.
