Magnetic moment of ^{207}Pb and the hyperfine splitting of ^{207}Pb^{81+}
We performed nuclear magnetic resonance measurements on lead(II) nitrate Pb(NO_{3})_{2} in aqueous solution and on the hexafluoridoplumbate(IV) [PbF_{6}]^{2−} ion in acetonitrile. Combined with new relativistic coupled cluster and relativistic density functional theory calculations of the shielding...

| description | We performed nuclear magnetic resonance measurements on lead(II) nitrate Pb(NO_{3})_{2} in aqueous solution and on the hexafluoridoplumbate(IV) [PbF_{6}]^{2−} ion in acetonitrile. Combined with new relativistic coupled cluster and relativistic density functional theory calculations of the shielding constant, we obtained a magnetic moment of μ(^{207}Pb)=0.59102(18)μ_{N} that is in clear disagreement with the tabulated value of +0.592583(9)μ_{N}. Similarly as in the case of ^{209}Bi this might be caused by an underestimated chemical shift in the aqueous solution of the nitrate. The consequences for a test of QED in strong magnetic fields by laser spectroscopy of the hyperfine splitting in Pb^{81+} and for the magnetic moments of short-lived lead isotopes are discussed. |
