Abstract

The energies and half-lives of isomeric transitions in Sn115 and Cd109 have been measured in pulsed proton beam bombardments of natural In and Ag at 17.5 MeV. The isomeric gamma rays were detected with a lithium-drifted germanium detector; time and energy information were obtained with the use of a 4096-channel two-dimensional analyzer. The values obtained were: Sn115: 115.9±1 keV, 100.7±2 keV, 498.0±1 keV; 166.4±10 μsec; and Cd109: 263±5 keV; 206±5 keV; 10.4±1 μsec. The gamma rays are quoted in their probable order of emission.
