Description

The partial beta-decay half-life for capture of M electrons in 163Ho is (4.0 +- 1.2) x 104 yr, and the 163Ho-163Dy mass difference is 2.3 +- 1.0 keV. From these independent results we deduce a half-life of (7 +- 2) x 103 yr and an upper limit on the electron neutrino mass of 1.3 keV. (orig.)
