Abstract
Foils of enriched (99.85%) were bombarded with particles with energies of 22.2, 29.5, 37.7, and 43.4 MeV after which -ray spectra were accumulated from the radioactive foils with a large Ge(Li) detector and a 4096-channel pulse-height analyzer system. The isotopes produced were determined by the -delayed rays and their corresponding half-lives. No chemical separation of the foils was performed.
Cross sections for a particular reaction were determined for each isotope and beam energy. The resulting excitation functions for the 13 reactions which were detected are presented, and are compared with similar reactions including those induced by on Cu isotopes. Possible reaction mechanisms are discussed. Direct reactions appear to be the principal reaction mechanism, especially at higher -particle energies where cluster-transfer reactions are common.
