Abstract

The updated evaluation of the decay data for the radionuclide ⁶⁸Ga is presented. The evaluated data have been obtained using the methodology adopted in the Decay Data Evaluation Project (DDEP). Particular attention is paid to obtaining the recommended value for the ⁶⁸Ga half-life from the discrepant data set. The recent half-life measurements do not improve the data consistency of this data set. The different statistical procedures are used to select the recommended value of 67.77 (14) min for the ⁶⁸Ga half-life.

Keywords: (68)Ga; Decay data; Discrepant data set; Evaluation; Half–life.
