A Method of Correction for Unresolved Levels in Fissile Nuclei

Abstract

A method of correcting for unresolved levels in fissile nuclei is described. The method is based on the distribution of the ratio of the reduced neutron width to the total width of a level. Calculations are carried out on three sets of data for 233U, and it is shown that approximately one-quarter of the resonance levels are undetected.
