SPECTRUM – A computer code for prompt fission neutron spectrum and prompt neutron multiplicity calculation

Abstract

The computer code SPECTRUM generates total prompt fission neutron spectrum, total prompt multiplicity, average energy of the spectrum and equivalent Maxwellian spectrum. Theoretical background employed in the calculations is that of Los Alamos model, with multiple chance fission, upgraded to allow a neutron incident energy dependence of the input parameters. The code handles the complete set of output data with a powerful graphical interface, allowing a comparison with reference data.
