Abstract：
The effect of angular momentum on the prescission particle multilplicity in the reaction of 10.6MeV/u ⁸⁴Kr(²⁷Al,binary fission) is studied using generalized fission diffused model.The prescission particle multilplicity and the scission time are found to increase with decreasing angular momentum. Most of the prescission particle is emitted before saddle. The consistency with the experimental particle multiplicity is obtained when we average with weight over angular momentum contribution to binary fission reaction. At the same time other factors which influence the prescission multiplicity and scission time are also discussed.
