gfactor of the 738 keV state inK43

The $g$ factor of the 738 keV second excited state in $^{43}\mathrm{K}$ has been measured using a perturbed angular correlation technique. A value for the half-life was also obtained. The level was populated via the $^{40}\mathrm{Ar}(\ensuremath{\alpha},p)^{43}\mathrm{K}$ reaction at 15 MeV with a pulsed beam. The spin precession was measured in an external magnetic field of \ensuremath{\sim} 3.8 and 5.4 kOe. The measured $g$ factor is + 1.28 \ifmmode\pm\else\textpm\fi{} 0.04, which is consistent with the reported spin of ${7/2}^{\ensuremath{-}}$. A comparison of the $g$ factor with other ${7/2}^{\ensuremath{-}}$ states in the odd potassium isotopes, and the ground state moments of the odd scandium isotopes reveal the state to be predominantly single particle in nature.
