Measurement of the half-life of /sup 163/Ho

Journal Article · · Phys. Rev. C; (United States)

In a continuing effort to explore electron-capture decay properties of /sup 163/Ho as a means of measuring the mass of the neutrino, we measured a half-life of 4570 +- 50 yr (95% confidence level) for /sup 163/Ho using isotope-dilution mass spectrometry. From this value of the half-life we infer an electron-capture Q value of approximately 2.65 keV using known atomic physics factors and an estimate of the nuclear matrix element based on the systematics of electron-capture ft values of other Ho isotopes.
