Target fragment angular distributions have been measured using radioanalytical techniques for the interaction of 3.0 and 12.0 GeV /sup 12/C with /sup 197/Au and /sup 238/U. For the reaction of 3.0 GeV /sup 12/C ions with /sup 197/Au and /sup 238/U, angular distributions were obtained for eight different target fragments (89< or =A< or =155), and seven different target fragments (43< or =A< or =149), respectively. In the interaction of 12.0 GeV /sup 12/C with /sup 197/Au and /sup 238/U, the angular distributions of six different target fragments (43< or =A< or =155) from each target were measured. All the fragments observed from /sup 197/Au target fragmentation show forward peaked angular distributions; from /sup 238/U target fragmentation, typical neutron-rich fission fragment nuclides show isotropic distributions in the laboratory system, while the rest of the fragments show forward peaked distributions similar to those observed in /sup 197/Au target fragmentation. The observed angular distributions are consistent with the values of previously measured F/B ratios and are compared with predictions of the intranuclear cascade model. The measured angular distributions are used to test the validity of two step vector model of high energy reactions.
