As output of the Point by model (taking into account entire fission fragment range) and most probable fragmentation approach (working with one average values parameters) not only prompt neutron quantities are provided but also γ-ray energy as a function Eγ(A) total <Eγ>. The almost linear behaviour <Eγ> multiplicity was observed experimentally in incident range where first chance is involved. This parameterised Z A fissioning nucleus. parameterisation validated calculations frame approach. results describe well experimental data measured J.FrŽhaut from thermal up to about 15 MeV for three systems 235U(n,f),237Np(n,f) 232Th(n,f).The provides pair very good agreement existing 252Cf(SF) 233U(nth,f). unique 235U(nth,f) described obtained using two methods excitation partition between complementary fragments.
