During this dissipative process, particles such as neutron, proton, alpha particle and gamma ray emit from the compound system. In the present work, the number of emitted particles using Langevin equation are calculated, dynamically. Obtained results for emitted alpha particles, protons and neutrons are compared with the experimental data. Also, we have studied the influence of the dissipative coefficient on these quantities. These results show that the dissipative coefficient affects the results, as well as the good agreement between the experimental data and theoretical results can be reproduced by using the dynamical approach.      Using Langevin dynamics and the dissipative nature of the fission process, we have studied dynamical variations of nucleus from the formation of the compound nucleus to separation stage of two fission fragments.
