Dynamics of Neutron Multiplicity in Heavy-Ion Induced Fusion-Fission Reactions

(M.Sc. Thesis)

Progress in nuclear physics in recent years made available the advance accelerators to produce energetic heavy ions.  These accelerated ions used to provide new reaction between them.  One of the important reactions in this area is the so-called heavy ion fusion fission reactions. In spite of many theoretical and experimental works in this area, there are some aspects that theoretical and experimental results not match. Evaporation residue especially neutron multiplicity, angular distributions, mass, charge and energy distribution of fission fragments and angle dependence of fission fragments spin are some of them. In this work we studied the mass and charge of fission fragments by producing a typical distribution function for asymmetric fission. Then we used this result to deduce the neutron multiplicity in different steps of fission processes in the base Statistical model of fission. Finally we studied dynamics of fission process using Langevin approach in the base of statistical simulation. The theoretical results obtained here compared with available experimental data for a few systems.
