Abstract
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 )
