Radiochemical investigations of Cu/sup 64,67/, Mo/sup 99/, Ag/sup 11/, Pd/sup and I/sup 121-135/ produced from irradiations of U/sup 238/ with highenergy protons are reported. Cross sections are given for proton energies between 0.5 and 6.2 Bev. Recoil properties from thick targets are reported for irradiations with 0.72and 6.2-Bev protons. All the products investigated at 0.72 Bev result from nuclear fission. Deposition energies of the same order as calculated for all nucleon-nucleon collision cascades. Excitation functions and the relative values of the deposition energies are reasonably well reconciled with nucleonic cascade followed by fission. Proton irradiations at 6.2 Bev produce Moss, Ag/sup 111/, Pd/sup 112/ and I/sup 131/-135/ by nuclear fission after depositing an average of <200 Mev in the struck nuclei. Cu/sup 64/ is probably not produced by binary fission. The neutron-deficient iodine isotopes are probably produced by a fast process. A correlation is suggested with fragment (A approximately 20 to 60) production. (auth)
