The radioactive decay half-life of the beta-emitter 111Ag has been measured using decay transitions identified using a high purity germanium (HPGe) gamma-ray spectrometer. The time series of measurements of the net peak areas of the 96.8, 245.4 and 342.1 keV characteristic gamma ray emissions following the decay of 111Ag were made over approximately 23 days, i.e. ~ 3 half-life periods. The measured half-life of the ground state decay of 111Ag was determined as 7.423 (13) days which is consistent with the Evaluated and Compiled Nuclear Structure Data File (ENSDF) evaluated 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.
