Abstract

Bound-state \mathrm\ensuremathβ^\mathrm\ensuremath- decay was observed for the fist time by storing bare ₆₆¹⁶³Dy⁶⁶⁺ ions in a heavy-ion storage ring. From the number of ₆₇¹⁶³Ho⁶⁶⁺ daughter ions, measured as a function of the storage time, a half-life of 47_\mathrm\ensuremath-5⁺⁵ d was derived. By comparing this result with reported half-lives for electron capture (EC) from the M₁ and M₂ shells of neutral ₆₇¹⁶³Ho, bounds for both the Q_EC value of neutral ₆₇¹⁶³Ho and for the electron-neutrino mass were set.
