Abstract
Measurements of neutron spectra in various media, obtained by the transit-time method in the fast pulse reactor IBR with a resolution of 0.04 μsec/m, are presented. The spectra of neutrons emerging from iron and nickel prisms of various thickness and also those from stainless-steel prisms are studied. The “fine structure” due to the resonance character of the cross sections of the media studied was clearly seen in the spectra measured. The experimental neutron spectra are compared with calculations made with a multigroup system of constants allowing for resonance self-screening of the cross sections. The reasons for the slight discrepancies found are analyzed.
