Abstract

The literature half-life value of ⁶⁵Ga is based on only one experiment carried out more than 60 years ago and it has a relatively large uncertainty. In the present work this half-life is determined based on the counting of the γ-rays following the β-decay of ⁶⁵Ga. Our new recommended half-life is t_1/2 = (15.133 ± 0.028) min which is in agreement with the literature value but almost one order of magnitude more precise.

Keywords: (65)Ga; Half-life; γ-spectroscopy.
