Abstrak

Recent discussions about the origin of the Gallium Anomaly have motivated a remeasurement of the half life of $^{71}$Ge. We have conducted three separate measurements using dedicated planar Ge detectors: one with $^{55}$Fe as a standard, one with $^{57}$Co as a standard, and one stand alone 71Ge measurement. Our results yield a half life of 11.468 +- 0.008 days, which is consistent with but significantly more precise than the currently accepted value. With this experiment, the potential explanation of the Gallium Anomaly being due to an unexpectedly long $^{71}$Ge half life has been ruled out, leaving the origin of the anomaly as an open question.
