Abstract
The magnetic moment of the 19/${2}^{\mathrm{\ensuremath{-}}}$ state in $^{39}\mathrm{K}$ has been measured by the transient field technique. The state was excited by the inverse reaction $^{12}\mathrm{C}$${(}^{32}$S,p\ensuremath{\alpha}${)}^{39}$K and the recoil nucleus traversed a thin Gd foil. Its absolute g factor, g=0.35(3), was obtained by an internal calibration, which makes use of the magnetic moment of the 15/${2}^{+}$ state in $^{41}\mathrm{Ca}$ also excited in the same reaction. A mean g factor for the states ${3}^{\mathrm{\ensuremath{-}}}$, ${5}^{\mathrm{\ensuremath{-}}}$ in $^{36}\mathrm{Ar}$, g=0.52(6), determined in a simultaneous measurement is consistent with the self-conjugate nature of the nucleus, giving further support to the validity of the field calibration. The experimental result agrees with shell-model predictions.
