Production of isotopes and isomers with irradiation of Z = 47–50 targets by 23-MeV bremsstrahlung

The irradiations of Ag to Sn targets by bremsstrahlung generated with 23-MeV electron beams are performed at the MT-25 microtron. Gamma spectra of the induced activities have been measured and the yields of all detected radionuclides and isomers are carefully measured and analyzed. A regular dependence of yields versus changed reaction threshold is confirmed. Many isomers are detected and the suppression of the production probability is observed with growing product spin. Special peculiarities for the isomer-to-ground state ratios were deduced for the 106 m Ag, 108 m Ag, 113 m In, 115 m In, and 123 m Sn isomers. The production of such nuclides as 108 m Ag, 115 m In, 117 g In, and 113 m Cd is of interest for applications, especially when economic methods are available.
