Activation measurements of the neutron radiative capture cross sections for 236U, 238U and 237Np

The method of activation relative to σn,p and σn,γ cross-sections for 197Au is used to measure cross sections of neutron radiative capture σn,γ for 236U, 238U and 237Np in the 160-1400 keV range and 235U fission cross sections in the 620-790 keV range. Processing of the obtained data is conducted according to the model of anisotropic and nonmonochromatic neutron source. It is shown that systematic errors of the obtained data don't exceed random errors
