We studied the special roles of proton-halo structure of 23Al on the fragmentation by using isospin dependent quantum molecular dynamics. In order to protrude the special roles of proton-halo structure on the reaction dynamics we compared the fragmentation multiplicity induced by proton-halo nucleus 23Al with those induced by a same mass stable nucleus 23Na. Fig.1 shows the fragmentation multiplicity FZ at freeze out time for the reactions 23Al +48Ca and 23Na +48Ca at impact parameter 6-1.0 fm as a function of beam energy. The mea-
We studied the special roles of proton-halo structure of 23Al on the fragmentation by using isospin dependent quantum molecular dynamics. In order to protrude the special roles of proton-halo structure on the reaction dynamics we compared the fragmentation multiplicity induced by proton-halo nucleus 23Al with those induced by a same mass stable nucleus 23Na. Fig.1 shows the fragmentation multiplicity FZ at freeze out time for the reactions 23Al ＋4sca and 23Na ＋48Ca at impact parameter b=1.0 fm as a function of beam energy.
