Title: Sub-barrier Fusion of Weakly Bound Nuclei

Abstract

Near-barrier fusion of neutron reach nuclei was studied within the semi-empirical channel coupling model of intermediate neutron rearrangement and within the time dependent three-body Schroedinger equation. A possibility of neutron transfer with positive Q-values considerably increases the barrier penetrability. A huge enhancement of deep sub-barrier fusion probability was found for light neutron reach weakly bound nuclei (such as 6He) that may be extremely important for astrophysical primordial and supernova nucleosynthesis.
