Beta decay of ⁴⁴V

We have calculated the β⁺ decay of the proton-rich nuclei ⁴⁴V 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 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 β⁺ energy window.
