Did we solve the old contradiction between microscopic and macroscopic experimental PFNS data?

Prompt Fission Neutron Spectra (PFNS) were analysed in the “dimensionless scale”. The important empirical facts were demonstrated. PFNS have the same shape for any isotopes and incident energy (<5MeV) for neutron induced and spontaneous fission. This is an additional argument for application of t...

Summary:Prompt Fission Neutron Spectra (PFNS) were analysed in the “dimensionless scale”. The important empirical facts were demonstrated. PFNS have the same shape for any isotopes and incident energy (<5MeV) for neutron induced and spontaneous fission. This is an additional argument for application of the scale method developed before. It was highlighted that spectrum shape changes slope at outgoing energy > 7 MeV. This fact was demonstrated with microscopic and macroscopic data. It was confirmed that old contradiction between microscopic and macroscopic data (mic-mac problem) has not yet been resolved.
