Abstract

The internal conversion spectrum from the decay Ag110m has been studied in an iron-free, double-focusing spectrometer. The K and in some cases L+M conversion electron intensities were measured for the following transitions in Cd110 : 446.5, 620.2, 657.6, 677.3, 686.5, 706.4, 743.9, 763.6, 818.0, 884.5, 937.4 and 1384.0 keV and the 433.8 and 613.7 keV transitions in Pb108. The energies were determined with an accuracy of a few parts in 104. The K conversion coefficients of the 2+ → 0+ 657.6, 4+ → 2+ 884.5 and 6+ → 4+ 937.4 keV transitions were measured by the internal-external conversion method to be (2.64±0.10)×10−3, (1.26±0.06)×10−3 and (1.12±0.08)×10−3, respectively. These αK results are in good agreement with the theoretical values for E2 transitions.
