The magnetic moment of the 22 μs isometric state in 38K

The g-factor of the $\text{τ}{}_{\mathrm{<mtext>1</mtext><mtext>2</mtext>}}\text{=22 μ}\text{s}\text{, J}{}^{\mathrm{\pi }}\text{=(7}{}^{\mathrm{+}}\text{), T=0}$ isomeric state at 3.46 MeV in ³⁸K has been measured by the differential spin precession method with the ${}^{35}\text{Cl}\text{(α,}\text{n}\text{)}{}^{38}\text{K}$ reaction. The result of g=+0.548 (μ=+3.836± 0.014 n.m.) is consistent with a pure configuration.
