Abstract
A SEARCH has been made for new radioactive isotopes produced by (γ,n) and (γ,p) reactions in various elements irradiated with 23-MeV. X-rays from a synchrotron. Whenever possible, a chemical identification of the element responsible for the radioactivity was made. A thin-window (1.7 mgm. cm.−2) Geiger counter was used for measuring the decay of the activities. The activities were usually too small and short-lived to permit any accurate measurement of the β-particle or positron energies.
