Neutron capture and transmission measurements have been made from 0.5 eV to 500 keV and have been analyzed to give parameters of resonances up to [similar to]100 keV. The average resonance spacing for [ital s]-wave resonances was determined to be 670

The purpose of this work is the precise determination of the /sup 238/U neutron capture yield (i.e., the probability of neutron absorption) as a function of neutron energy with the highest available neutron energy resolution. The motivation for this

A model for gamma-ray cascade de-excitation of a nucleus derived from the Maxwellian energy distribution function while imposing energy conservation was investigated. Energy distributions and multiplicities and their averages were found over a range

The neutron capture cross section of 54 Fe has been measured with 0.2% energy resolution from 2.5 to 500 keV. A large and significant correlation is observed between the s-wave reduced neutron widths and the corresponding total radiative widths. The
