Description
Using the time-of-flight method on the IBR-30 pulsed neutron source in the 0.465-200 keV energy range, measurements were carried out to determine the total transmissions and the self-indication functions in the radiative capture cross-section for metallic samples of 238U of various thickness. For radiative capture the dependence of the measured data on the multiplicity of registration of gamma rays was investigated. From the experimental data the authors derived the group-averaged total cross-sections (for the BNAB data system) and also the resonance self-shielding factors of the total and radiative capture cross-sections. The average resonance parameters - the neutron and radiative strength functions and scattering radii - were evaluated with the aid of the EVPAR program. The results are compared with other data.
