Fission fragment angular distributions were measured with gold surface barrier detectors for proton-induced 6/, U/sup 238/, Np/sup 237/, and Pu/ sup 239/ . Absolute fission cross sections were determined for U/sup 233/ and U/sup 238/. The proton projectile energy range of 4 to 12 Mev was obtained with the Argonne tandem Van de Graaff. Over this energy range the fission cross section of U/sup 233/ changed by a factor exceeding a million. Total reaction cross sections were calculated for the highly fissionable U/sup 233/ target by applying small corrections (3 to 20%) for the spallation cross sections. These reaction cross sections are compared with theoretical values deduced from surface absorption optical-model calculations with parameters of Perey and Wilkins. (auth)
