Abstract

Fission cross-section ratios of 238U/235U, 238U/237Np, 235U/237Np and 239Pu/235U were determined in the range of 13.5-14.8 MeV neutron energy. Neutrons were produced by a 180 kV Cockcroft-Walton generator using the T(d,n)4 He reaction. The fission events from samples were detected with 12 μm Makrofol KG polycarbonate foils. A 2π geometry was used. The etched foils were evaluated by a jumping spark counter (JSC). The trends of the relative cross sections within the limits of errors are in good agreement with those deduced from various compilations.
