Abstract
Fission gamma-ray yields from Np-237 low-energy resonances are studied by using the Dubna IBR-30 pulsed reactor. A multiplate fission chambe r with 1.5 g of high-purity Np-237 for detecting fission events and a large 6-section liquid scintillation detector for detecting 3 or more photons in coincidence with fission fragments are used to measure fiss ion gamma-ray yields. A significant 1/Gamma(f) dependence is found for gamma-ray yields in Np-237 resonances. This experimental result can b e attributed to prefission gamma ray emission-that is, to the occurren ce of the process (n, gamma f).
