Detailed validation of two deterministic models of prompt emission. Systematic behaviours of residual quantities from the sequential emission

The results of the Point-by-Point (PbP) model and sequential emission modellings describe very well the recent experimental data of ²³⁵U(n,f). The application of the sequential emission treatment to 49 fission cases has emphasized systematic behaviours of different quantities characterizing the fragments and the prompt emission. These allowed the determination of a general form of the residual temperature distribution for each emission sequence and the inclusion of sequential emission into the Los Alamos model (LA model) of prompt emission. The comparison of the LA model calculation for prompt neutron centre-of-mass spectrum agrees well with experimental data
