Abstract
Using multi-group diffusion equation and eigenfunction expansion method, the results for time- and energy-dependent fast neutron spectra are reported for an infinite iron assembly. The nuclear cross-sections used are taken from vitamin-C nuclear data file. The results are presented at short times (0–50 nsec) as well as at large times (50–500 nsec) after the injection of a mono-energetic pulse of 14.47 MeV. Following the pulse, the time behaviour of neutrons corresponding to different energy groups has been discussed. The values of mean slowing down times and of most probable times have been obtained for each energy group.
