Fusion reaction of halo nuclei: A real-time wave-packet method for three-body tunneling dynamics
Abstract
We investigate fusion cross section of a nucleus with a valence neutron, using the time-dependent wave-packet method. For a stable projectile, in which the valence neutron is tightly bound (en < -3 MeV), the neutron could enhance the fusion probability when the matching condition of orbital energies are satisfied. In contrast, for a halo nucleus, in which the binding energy of the neutron is very small (en>-1 MeV), the fusion probability is hindered by the presence of the weakly bound neutron.
