Bound-state {beta}{sup {minus}} decay was observed for the fist time by storing bare {sub 66}{sup 163}Dy{sup 66+} ions in a heavy-ion storage ring. From the number of {sub 67}{sup 163}Ho{sup 66+} daughter ions, measured as a function of the storage time, a half-life of 47{sub {minus}5}{sup +5} d was derived. By comparing this result with reported half-lives for electron capture (EC) from the {ital M}{sub 1} and {ital M}{sub 2} shells of neutral {sub 67}{sup 163}Ho, bounds for both the {ital Q}{sub EC} value of neutral {sub 67}{sup 163}Ho and for the electron-neutrino mass were set.
