N2 - The main purpose of this work was to improve the experimental value θ of the 32S(n, p)32P reaction cross section for a fission neutron spectrum. The sample in a cadmium box was centred on the axis of an enriched uranium disk irradiated by a thermal neutron beam. The absolute value of the thermal flux was determined by activation of a gold detector. The absolute value of the fast flux at the sample was calculated taking into account the detector-uranium geometry. The average cross section θ was deduced from an absolute measurement of the sample activity. The results are: for 32S(n, p)32P: θ = 65 ± 3 mb, for 27Al(n, α)24Na: d = 0·63 ± 0·03 mb.
