Abstract:
Effect of the rotational degree of freedom of In nucleus in three dimension space on prescission particle emission in 10.6MeV/u and 8.5MeV/u 84Kr+27Al collisions was studied in the framework of a statistical model. The calculation results show that for the latter incident energy,particle emission is insensitive to the rotational degree of freedom,while for the former one,the incorporation of this factor leads to the reduction of the extracted fission delay time from 20×10-21s to 7.5×10-21s,indicating the existence of this effect. The result also demonstrates that this effect is unable to completely account for the experimental data. In addition,the effect of rotational degree of freedom on particle evaporation prior to scission was found to depend on the excitation energy.
