Precise half-life measurement of the superallowed beta(+) emitter (10)C
Abstract
The half-life of (10)C 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 (10)C is the lightest superallowed 0(+)-> 0(+) beta(+) emitter, its ft value has the greatest weight in setting an upper limit on the possible presence of scalar currents.
