Superallowed Fermi decay ofGa62

The superallowed ${\beta }^{+}$ decay of ${}_{}{}^{62}{}_{}{}^{}\mathrm{Ga}$ has been studied, using plastic and semiconductor $\Delta E-E$ telescopes. The reaction ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$(${}_{}{}^6{}_{}{}^{}\mathrm{Li}$,$2n$)${}_{}{}^{62}{}_{}{}^{}\mathrm{Ga}$ was used to produce ${}_{}{}^{62}{}_{}{}^{}\mathrm{Ga}$, with $E_{{}_{}{}^6{}_{}{}^{}\mathrm{Li}}=25\mathrm{}$ MeV. A half-life of 116.34±0.35 ms was obtained, and the total decay energy $Q_{\mathrm{EC}}$ was measured to be 9171±26 keV. After applying radiative and charge-dependent corrections, the "corrected" $\mathrm{ft}$ value $\mathcal{F}t=3081\mathrm{}\pm 47$ s was obtained, in excellent agreement with the value from Fermi decays in $A\le 54$ nuclei.
