Query: Half-life measurement of 65Ga with gamma-spectroscopy   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
gamma-rays following the beta-decay of 65Ga. Our new recommended half-life is
15.133 +- 0.028 min which is in agreement with the literature value but almost
one order of magnitude more precise.
