The ${\mathrm{F}}^{19}(\alpha ,n){\mathrm{Na}}^{22*}$ reaction which takes place in a source of ${\mathrm{Po}}^{210}$ dissolved in HF was used to prepare ${\mathrm{Na}}^{22*}$ in the 0.66-MeV 0+ excited state. The subsequent 0+→1+→3+ $\gamma -\gamma$ angular correlation was magnetically perturbed in order to measure the $g$ factor of the 0.58-MeV first excited state. A value $g=+0.535\mathrm{}\pm 0.010$ was obtained. The energy and half-life of the 1+ state were remeasured as 583.0±0.5 keV and (243±2)×${10}^{-9\mathrm{}}$ sec, respectively.
