Beta decay of ${}_{}{}^{44}{}_{}{}^{}\mathrm{V}$

We have calculated the ${\mathrm{\beta }}^{+}$ decay of the proton-rich nuclei ${}_{}{}^{44}{}_{}{}^{}\mathrm{V}$ in the full fp-shell valence space. Using the standard quenching factor 0.77 for the Gamow-Teller (GT) operator we obtain a theoretical half-life of 71 ms in good agreement with the experimental value ${\mathit{t}}_{1/2}$=90±25 ms. We also compute the Gamow-Teller strength functions corresponding to the decays of the $2^{+}$ ground state and $6^{+}$ isomer state. Our results indicate that 80% of the total GT strength falls within the ${\mathrm{\beta }}^{+}$ energy window.
