Angular distributions and differential range curves at angles of 15°, 90°, and 165° have been obtained by radiochemical methods for several representative products which recoil out of thin uranium targets irradiated with 2.2-GeV protons. Mean momenta observed at 90° to the beam direction are 133, 125, and 125 (MeV amu) 1/2 for the neutron-excess isotopes Ba140, Mo99, and Sr91, but only 96 and 104 (MeV amu) 1/2 for the neutron-deficient products Ba131 and Pd103. The neutron-deficient isotopes have broader momentum distributions and more forward-peaked angular distributions than do the neutron-excess products. Results are discussed in terms of a two-step vector model, i.e., a fast nucleonic cascade followed by fission or another slower de-excitation step. The observed spectra and angular distributions for all the isotopes are consistent with such a model. Observed mean velocities are compared to those predicted by a liquid-drop theory of fission. It is concluded that products in the mass-90-to-140 range are produced primarily by a conventional fission mechanism. However, some contribution of a spallationlike process appears necessary to account for low-velocity fragments in the case of the neutron-deficient products (particularly Ba131).
