Structure effects on fission yields

Abstract

The structure effects of the fission fragments on their yields are studied within the statical theory with the inputs, like, excitation energies and level density parameters for the fission fragments at a given temperature calculated using the temperature dependent relativistic mean field formalism (TRMF). For the comparison, the results are also obtained using the finite range droplet model. At temperatures $T=1-2$ MeV, the structural effects of the fission fragments influence their yields. It is also seen that at $T=$ 3 MeV, the fragments become spherical and the fragments distribution peaks at a close shell or near close shell nucleus.
