Excitation Functions for Spallation Reactions on Cu

Abstract

Excitation functions have been measured for 190-Mev deuterons from the 184-inch Berkeley cyclotron on the natural isotopic mixture of ${\mathrm{Cu}}^{63}$ and ${\mathrm{Cu}}^{65}$. Chemical separation of Zn, Cu, Ni, Co, Fe, and Mn has been performed and the yields of several of the radioactive isotopes of these elements have been measured as a function of deuteron energy. The results seem to be in agreement with Serber's theory of high energy processes and with other information on the yields of nuclear reactions at these energies.
