Decay properties ofGd146

${}_{}{}^{146}{}_{}{}^{}\mathrm{Gd}$ decay has been measured and a new ${}_{}{}^{146}{}_{}{}^{}\mathrm{Eu}$ level scheme established with excited levels at 114, 230, 384, 421, 498, and 690 keV having spins and parities of $3^{-}$, $2^{-}$, $1^{-}$, ${\mathrm{}\left(2\right)\mathrm{}}^{-}$, and $2^{-}$, respectively. From experimental relative $P_k$ values in ${}_{}{}^{146}{}_{}{}^{}\mathrm{Gd}$ electron capture decay and from $\frac{{\beta }^{+}}{\mathrm{EC}}$ ratios measured in ${}_{}{}^{146}{}_{}{}^{}\mathrm{Gd}$ and ${}_{}{}^{150}{}_{}{}^{}\mathrm{Dy}$ decay, lower and upper limits for the ${}_{}{}^{146}{}_{}{}^{}\mathrm{Gd}$ and ${}_{}{}^{150}{}_{}{}^{}\mathrm{Dy}$ decay energies have been determined to be $950<\mathrm{}{Q}_{\mathrm{EC}}\left({}_{}{}^{146}{}_{}{}^{}\mathrm{Gd}\right)<\mathrm{}1054\mathrm{}$ keV and $1710<\mathrm{}{Q}_{\mathrm{EC}}\left({}_{}{}^{150}{}_{}{}^{}\mathrm{Dy}\right)<\mathrm{}1814\mathrm{}$ keV. The upper limits on these decay energies were smaller than the extrapolated masses indicated. The ${}_{}{}^{146}{}_{}{}^{}\mathrm{Gd}$ decay energy is in accordance with recent reaction data.
