The ${\ensuremath{\beta}}^{+}$ decay of $^{47}\mathrm{Cr}$ (${J}^{\ensuremath{\pi}}$,T${=(3/2)}^{\mathrm{\ensuremath{-}}}$,(1/2)) has been studied following its production by the $^{9}\mathrm{Be}$${(}^{40}$Ca, 2n${)}^{47}$Cr reaction at E${(\mathrm{}}^{40}$Ca)\ensuremath{\approxeq}90 MeV. In addition to the previously reported superallowed decay to the mirror state (i.e., the $^{47}\mathrm{V}$ ground state), we observe a (3.7\ifmmode\pm\else\textpm\fi{}1.2)% allowed ${\ensuremath{\beta}}^{+}$ branch to the ${(5/2)}^{\mathrm{\ensuremath{-}}}$ state at 87 keV in $^{47}\mathrm{V}$. These two branches appear to dominate the decay of $^{47}\mathrm{Cr}$; an upper limit of less than 0.5% is set on possible \ensuremath{\gamma} rays, other than the 87-keV \ensuremath{\gamma} ray, in the range of 15 to 2800 keV. Measurement of the time decay of the 87-keV \ensuremath{\gamma} ray establishes a value of ${T}_{1/2}$=508\ifmmode\pm\else\textpm\fi{}10 ms for the $^{47}\mathrm{Cr}$ half-life which is in significant disagreement with two previously reported values. The present work utilized Ge spectroscopy and a He-jet system for transport of the beam-induced radioactivity, as opposed to previous measurements which used a plastic scintillator to detect positrons and either a He-jet chopper or a slow beam-pulsing system. A summary of decay data for the complete ${f}_{7/2}$ shell series of mirror nuclei is also presented.
