Abstract
The half-life of has been measured to be 19.310(4) s, a result with 0.02% precision, which is a factor of three improvement over the best previous result. Since is the lightest superallowed emitter, its value has the greatest weight in setting an upper limit on the possible presence of scalar currents.
