Description
Spectra of neutrons with initial energy of 14 MeV leaking from an uranium sphere are measured. A time-of-flight spectrometer and recoil protons spectroscopy in proportional counters are used. The fisson reaction rate for 235U, 237Np, 232Th and 238U with fission chambers and the activation reaction rate for the reactions 115In (n,n'), 27Al (n,α), 65Cu (n,2n) and 203Th (n,2n) are determined. Comparision of the experimental results with those calculated by constants from the ENDF/B-IV and ENDL-75 libraries using the BLANK, ANISN and MORSE programs is made. 3 figs., 1 tab., 8 refs
