In the previous publications we have demonstrated that the four-dimensional Langevin model developed by our group can describes well the nuclear fission of actinides. Now we examine the predictive power of the Langevin model in lighter system than actinides, such as ¹⁸⁰Hg. Especially, we focus on the effects of (1) multi-chance fission based on Hauser-Feschbach model, and (2) on the temperature-dependence of shell effects recently examined by our group, then investigate their influence on nuclear fissions.
