Abstract:
The systematic behaviour of the experimental ratio of the heavy fragment prompt neutron multiplicity to the multiplicity of the fragment pair allows parameterizations of the corresponding excitation energy ratio. The excitation energies of the fission fragments calculated by modeling at scission were parameterized using simple linear functions. The validation of these parameterizations was done by Point-by-Point model calculations for 235U(n,f) and 239Pu(nth,f) benefiting of experimental data of prompt neutron multiplicity as a function of fragment mass. Similar excitation energy parameterizations are performed for other fission systems for which experimental data are very scarce or totally missing. Using these parameterizations in the frame of Point-by-Point model, prompt emission data can be predicted for any fissioning systems.
