Abstract

A dynamical Monte Carlo simulation based on the three dimensional Langevin equations applied to obtain γ - ray multiplicity emitted from highly excited compound nucleus. In induced fusion-fission reaction, resultant compound system is looses a part of its energy via γ - ray emission both before and after saddle point that can be measure using proper apparatus. In this paper, γ - ray multiplicity have been measured and calculated following the B¹⁰+Np²³, B¹¹+ Th²³², C¹²+Th²³², O¹⁶ +Th²³² reactions. Comparison of experimental and calculated data suggests significant effect of the asymmetry parameter.
