摘要

<正>We studied the special roles of weak boose neutron-halo nuclear structure of 19B on the fragmentation by using isospin dependent quantum molecular dynamics. In order to compare and protrude the special roles of neutron-halo-nuclear structure on the reaction dynamics process we compared the results of fragmentation multiplicity induced by neutron-halo nucleus 19B with those induced by a same mass stable nucleus 19F under the same incident channel condition. In order to study systematically the evolution of fragmentation multiplicity FM with increasing beam energy, Fig.1 shows the FM at freeze out time as a function of beam energy. The
