DECAY OF 110MAG - GAMMA-RAY ENERGY AND INTENSITY STANDARDIZATION

The energies and intensities of the transitions from the decay of 110mAg have been carefully measured with three different systems which use Ge(Li) detectors. The following energies in keV and intensities in parentheses were determined for standards: 446.77 ± 0.04 (3.5 ± 0.2), 620.22 ± 0.03 (2.9 ± 0.2), 657.71 ± 0.03 (100), 677.55 ± 0.03 (12.2 ± 0.7), 686.80 ± 0.03 (7.4 ± 0.6), 706.68 ± 0.04 (17.2 ± 07), 744.19 ± 0.04 (4.4 ± 0.4), 763.88 ± 0.04 (24.0 ± 0.8), 818.00 ± 0.04 (7.8 ± 0.3), 884.67 ± 0.04 (79.6 ± 2.0). 937.48 ± 0.04 (36.5 ± 1.1), 1384.22 ± 0.04 (27.7 ± 0.8) 1475.73 ± 0.04 (4.5 ± 0.2), 1504.90 ± 0.08 (14.8 ±0.4) and 1562.22 ± 0.06 (1.33 ± 0.06). All these transitions fit into the well-known decay scheme of 110mAg. Transitions previously reported at 566.0, 667.2, 753.0, 785.0 and 1443.0 keV were not observed, but weak new transitions at 626, 997 and 1334 keV were observed. Transitions of 434.00 ± 0.10, 614.37 ± 0.10 and 722.95 ± 0.08 keV were observed from the decay of 108mAg. © 1969.
