Decay ofAg103

The nucleus ${\mathrm{Ag}}^{103}$ has been studied with scintillation beta and gamma spectrometers. The isotope was produced by a ($p, \gamma$) reaction on ${\mathrm{Pd}}^{102}$ with low-energy protons (∼3 MeV) to exclude production of ${\mathrm{Ag}}^{104}$. In addition to the gamma rays already reported in the literature, prominent gamma rays at 1010 keV, 1160 keV, and 1280 keV have been observed. A new positron group of 1.57-MeV end-point energy has also been observed. Beta-gamma coincidences, gamma-gamma coincidences, and sum studies have been made, and on the basis of those measurements a level scheme of ${\mathrm{Pd}}^{103}$ is proposed.
