| Abstract: | 150m, 152mHo, and149Dy were produced by fusion-evaporation reactions of40Ar with targets of natural indium and114Cd. Theβ-decays of the isotopes were reinvestigated with emphasis on high-excitation daughter states. The decay energies for selectedβ-transitions were measured from electron-capture to positron-decay ratios. Corrections forγ-feeding from higher-lying states were taken into account. The following QEC-values were derived for150mHo,152mHo, and149mDy of 6819 ( ?100 +117 , 6263 ( ?80 +89 ), and 3914 ( ?52 +76 ) keV, respectively. |
