Abstract:  The standard statistical model of Bohr and Wheeler was sufficient for a long time to describe the observed effects of nuclear fission till the availability of heavy-ion beams. Bohr and Wheeler gave the explanation for the fission process and the decay rate of nuclear fission. In contrast to the statistical model’s predictions, experimentally it was found that more particles are being emitted during fission process. To understand the experimental observations with the theoretical calculations, Kramer introduced the concept of dynamical effects in fission process. The role played by nuclear viscosity or dissipation in fission process, particularly in heavy ion fusion is of great interest. Thus the experiments were performed to study the light particles multiplicities in ^210,212Rn compound nuclei. To get the insight into the dynamics of fissioning nuclei moving source technique was used to extract multiplicity along with the pre-scission, post-scission and near scission contributions from the total yield spectra. Studying the fission mechanism using the different probes helped in understanding the detailed reaction dynamics.
