| The aim of this study is to know the behavior of fission probability as function of neutrons energy of various fission nucleuses (231Th, 233Th, 235U, 237U, 239U, 241Pu, 243Pu) at the same energy range of descending neutrons (0.5 MeV to 2 MeV). The fission probability is considered as a principal effective factor in measuring the fission cross section of fissing materials. In this work we found that, the fissing materials at the energy range of descending neutrons decreased as a result of increasing neutron energy. In this study, I conclude the empirical relations by the fitting method in which the probability fission value can be estimated as a function for neutrons energy (0.5MeV-2MeV) and for various fission nucleuses, for instant the empirical formula for thorium atom ( 231 ) Th as below : 0.1707 0.6688E (MeV ) nf P = e- n | ||
