Deexcitation processes in nuclear reactions. Progress report, May 1, 1972- -April 30, 1973

Abstract

High-and low-energy nuclear reaction studies have been performed. The high-energy projects include a comparative study of the nuclear reactions of silver with 300-and 11.5-GeV protons; a comparative study of cross sections and recoil properties of products in the A=120-140 mass region from the inter-238 action of U with 300-and 11.5-GeV protons; measurement of the charge dispersion and recoil properties of products in the A0131 region from the inter-197 action of Au with 11.5 GeV protons; study of the energy dependence of the recoil properties of neutron deficient products with A=131 from the inter-238 action of U with high-energy protons; differential range study of products with A%131 from the interaction of U with 11.5 GeV protons; study of a frag-238 24 mentation product, Na, in pion-induced reactions. The low-energy research includes a study of the energy dependence of isospin mixing in the Ga com-69 49 pound nucleus; tests of the independence hypothesis in the decay of the V, 52 55 69 Cr, Mn, and Ga compound nuclei formed in protonand a-induced reactions; a test of the independence hypothesis in the decay of Br formed in reactions 75 induced by C and 0 ions. 12 16
