9、 investigated by using isospindependent quantum molecular dynamics. In order to compare and protrude the special role of neutron-halo-nucleus19B, the momentum dissipation induced by a same mass stable nucleus19F was investigated under the same incidentchannel condition. It is found that the weak bou
10、nd neutron-halo structure of19B weakens the momentum dissipationprocess compared to those induced by stable nucleus19F in the lower energy region. However the nuclear stopping ofcolliding system with the neutron-halo nucleus19B decreases gradually with the increasing beam energy. For all of masstarg
11、ets and impact parameters the neutron-halo nucleus19B weakens the momentum dassipation process.Key wordsneutron-halo nucleus, momentum dissipation, heavy ion collisionReceived 21 January 2005 *Supported by Major State Basic Research Development Program in China (G2000077400), Key Project of National NaturalScience Foundation of China (10435080), National Natural Science Foundation of China (10447006 ) and The CAS KnowledgeInnovation Project (KJCX2-SW-N02) 1)E-mail:
