摘要
We have measured the half-life of S-30, the parent of a superallowed 0(+)-> 0(+) ss transition, to a high precision using very pure sources and a 4 pi proportional gas counter to detect the decay positrons. Our result for the half-life is 1.179 92(34) s. As a by-product of this measurement, we determine the half-life of its daughter, P-30, to be 2.501(2) min.
