Nature of problem:
Prompt fission neutron spectrum and average prompt neutron multiplicity are calculated.
Prompt fission neutron spectrum and average prompt neutron multiplicity are calculated in the frame of Los Alamos model with multiple fission chances. Energy dependence of the compound nucleus cross sections of inverse process and incident neutron energy dependence of model parameters are considered.
Only the neutrons evaporated prior to scission are considered, the pre-equilibrium effects are neglected. The maximum number of compound nuclei undergoing fission (or fission chances) is four.
Dependence on the incident neutron energy of model parameters, graphics and possibility to compare the results with data of external input files.
Five minutes in the option of the energy dependence of the compound nucleus cross sections of the inverse process and less than 1 minute in the option of constant compound nucleus cross sections.
