Abstract

The neutron induced fission cross-section of ²³⁵U was measured up to 30 keV at a 30 m flight-path of the CBNM Linac. The fission reaction rate and the neutron flux were determined simultaneously with surface barrier detectors placed on each side of back-to-back ²³⁵U and ¹⁰B layers. The fission cross-section was calculated assuming a 1 v-behaviour of the ¹⁰B(n, α)⁷Li cross-section and normalized to ∫^11eV_7.8eV σ_f(E) dE = 240 barn.eV. The average fission cross-section was calculated in several energy regions and compared with other results. Also the fission integral ∫^1000eV_1eV σ_f(E) dE was calculated yielding 16.16 barn.keV; for the epicadmium resonance integral we obtained I_f = 280 ± 7 barn.
