The recently published paper "Half-life of Ge-71 and the gallium anomaly", co-authored by UCBNE Professor Eric Norman has been chosen as an "Editor's Suggestion" in the journal Physical Review C. 

A summary of the paper put out by PRC:

Several past experiments such as SAGE, GALLEX, and BEST reported lower than expected neutrino capture rates on Ga-71. The origin of this so-called “gallium anomaly” could potentially indicate new neutrino physics, unless there was a more mundane explanation. Because the measured half- life of the electron-capture decay of Ge-71 can be used to calculate the neutrino-capture cross section on Ga-71, the authors carried out three separate measurements to determine the half-life of Ge-71 with high precision. Their new result of 11.468±0.008 days for the Ge-71 half-life is consistent with the currently accepted value, but significantly more precise. It rules out an unexpectedly long Ge-71 half-life as a potential explanation of the puzzling anomaly, leaving the anomaly’s origin an open question.
