Abstract

Fission gamma-ray multiplicity measurements in low energy 233U, 235U, 237Np and 239Pu fission resonances were made by using the Dubna pulsed reactor IBR-30 as a resonance neutron source. A large 6-section liquid scintillation detector and fission chambers with a combination of (233U-235U), (237Np-235U) and (239Pu-235U) targets were used for detecting 3 or more fission gamma-quanta in coincidence with a fission fragment pulse. The fission gamma-ray multiplicity data from these measurements are discussed relative to the prompt fission neutron multiplicity data available for low energy 233U, were measured over the neutron energy interval around 40 eV. Correlation between the fission gamma-ray multiplicities and the fission widths Гf of measured 237Np resonances was observed, which might be explained by the (n,γf) reaction.
