Unusual backward enhancement in the angular distribution of products from the interaction of /sup 238/U with 400-GeV protons
Angular distributions of various Mg, Sc, Cu, Ag, and Ba nuclides produced in the interaction of /sup 238/U with 400-GeV protons have been measured. While all the angular distributions peak at approx. 90/sup 0/, those obtained for certain products are characterized by greater backward than forward emission in the laboratory system. This category includes both neutron-deficient and neutron-excess Sc fragments as well as neutron-deficient Cu and Ag nuclides.
