Measuring multiplicity and total energy of gamma radiation under 235U fission by resonance neutrons

Using the IBR-30 pulsed neutron source, spectroscopic studies of γ radiation, accompanying 235U fission by resonance neutrons with 0.7 to 36 eV energy, are carried out. The ionization chamber, containing 10 g of uranium, enriched in 235U isotope up to 90%, and Ge(Li)-gamma detector with volume of ∼ 30cm3 and 2.8 keV energy resolution at 1333 keV operated in the coincidence mode. The method of multidimensional analysis was used. As a result of the device spectrum, reconstruction a γ spectrum in the 0.1-1.6 MeV energy range is determined. The γ radiation integral characteristics: multiplicity, total and average energy values, are calculated. The average energy values for 3- and 4- resonances are given
