      abstract     = {Short-lived 46 Cr, 50 Fe and 54 Ni were studied by
                      isochronous mass spectrometry at the HIRFL-CSR facility in
                      Lanzhou. The measured precision mass excesses (ME) of 46Cr,
                      50Fe and 54Ni are −29471(11) keV, −34477(6) keV and
                      −39278(4) keV, respectively. The superallowed 0+ → 0+
                      β-decay Q values were derived to be Q EC (46 Cr) = 7604(11)
                      keV, Q EC (50 Fe) = 8150(6) keV and Q EC (54 Ni) = 8731(4)
                      keV. The values for 50Fe and 54Ni are by one order of
                      magnitude more precise than the adopted literature values.
                      By combining the existing half-lives and branching ratios,
                      we obtained the corrected Ft values to be Ft(50Fe) =
                      3103(70) s and Ft(54Ni) = 3076(50) s. The main contribution
                      to the Ft uncertainties is now due to β-decay branching
                      ratios, still, more high-precision measurements of the
                      half-lives, the masses, and especially the branching ratios
                      are needed in order to satisfy the requirements for a
                      stringent CVC test.},
