The excitation curve for the reaction Th/sup 232/(n,2n)Th/sup 231/ was measured by the activation method from the threshold energy, 6.34 Mev, to 20.4 Mev, relative to the kown cross section for the S/sup 32/(n,p)/sup 32/ reaction. Monoenergetic neutrons were obtained from the D(d,n)He/sup 3/ and T(d,n)He/sup 4/ reactions by employing a tandem Van de Graaff accelerator. From threshold to 9.0 Mev, the (n,2n) cross section rose rapidly, reaching its maximum value of 1.88 plus or minus 0.09 barns in the region of 9.5 to 11.0 Mev. Above 11.5 Mev the (n,2n) cross section decrease owing to competition of the (n,3n) and (n,2nf) reactions, and at 20.4 Mev it had a value of 0.22/sub 5/ plus or minus 0.01/sub 5/ barns. (auth)
