Description

The special role of neutron-halo nucleus 19B on the momentum dissipation was investigated by using isospin dependent quantum molecular dynamics. In order to compare and protrude the special role of neutron-halo-nucleus 19B, the momentum dissipation induced by a same mass stable nucleus 19F was investigated under the same incident channel condition. It is found that the weak bound neutron-halo structure of 19B weakens the momentum dissipation process compared to those induced by stable nucleus 19F in the lower energy region. However the nuclear stopping of colliding system with the neutron-halo nucleus 19B decreases gradually with the increasing beam energy. For all of mass targets and impact parameters the neutron-halo nucleus 19B weakens the momentum dissipation process. (authors)
