Measurement of the nuclear magnetic dipole moment of Au197 and hyperfine structure measurements in the ground states of Au197, Ag107, Ag109 and K39

Abstract

Using an atomic beam magnetic resonance apparatus the nuclear magnetic dipole momentμ I of the stable isotope Au197 was measured directly with the doublet method. The result isμ I(Au197)=0.143491 (9)μ n, uncorrected for atomic diamagnetism. Further hyperfine structure measurements were performed in the ground states of K39, Ag107, Ag109 and Au197 with the following results:Δv(K39)=461.719723 (38) MHzΔv(Ag107)=1712.512111 (18) MHzΔv(Ag109)=1976.932075 (17) MHzΔv(Au197)=6099.320184 (13) MHzg J(Ag107)/g J(K39)=1.0000260 (20)g J(Au197)/g J(K39)=1.0005076 (20).
