Abstract
The half-life of 66Ga, an isotope very important for high-energy efficiency calibration of gamma-detectors, has been measured using gamma-spectroscopy. In order to reduce systematic uncertainties, different source production methods and gamma-counting conditions have been applied. A half-life value of 9.312 +- 0.032 h has been obtained in agreement with a recent measurement but in contradiction with some of the earlier results.
