Abstract

The precise half-life measurement for the superallowed 0⁺→0⁺ emitter ⁷⁴Rb was done. The measured data were collected at the radioactive beam facility (ISAC) at TRIUMF using a beam of 4000 ⁷⁴Rb ions/sec. It was found that since the axial-vector decay strength was zero for superallowed Fermi 0⁺→0⁺ β decays, the intensities were directly related to the weak vector coupling constant.
