Half-life determination of the ground state decay of super(111)Ag

The radioactive decay half-life of the -emitter super(111)Ag has been measured using decay transitions identified using a high purity germanium gamma -ray spectrometer. The time series of measurements of the net peak areas of the 96.8 keV, 245.4 keV and 342.1 keV gamma -ray emissions following the d...

Zusammenfassung:The radioactive decay half-life of the -emitter super(111)Ag has been measured using decay transitions identified using a high purity germanium gamma -ray spectrometer. The time series of measurements of the net peak areas of the 96.8 keV, 245.4 keV and 342.1 keV gamma -ray emissions following the decay of super(111)Ag were made over approximately 23 days, i.e. ~3 half-life periods. The measured half-life of the ground state decay of super(111)Ag was determined as 7.423 (13) days which is consistent with the Evaluated Nuclear Structure Data File (ENSDF) recommended half-life of 7.45 (1) days at k=2. Utilising all available experimental half-life values, a revised recommended half-life of 7.452 (12) days has been determined.
