Query: Q-values of the Superallowed beta-Emitters 26m-Al, 42-Sc and 46-V and
  their impact on V_ud and the Unitarity of the CKM Matrix   The beta-decay Q_EC-values of the superallowed beta emitters 26m-Al, 42-Sc
and 46-V have been measured with a Penning trap to a relative precision of
better than 8x10^-9. Our result for 46-V, 7052.72(31) keV, confirms a recent
measurement that differed significantly from the previously accepted
reaction-based Q_EC-value. However, our results for 26m-Al and 42-Sc,
4232.83(13) keV and 6426.13(21) keV, are consistent with previous
reaction-based values. By eliminating the possibility of a systematic
difference between the two techniques, this result demonstrates that no
significant shift in the deduced value of V_ud should be anticipated.
