Precision measurement of the 43Ca+ nuclear magnetic moment

We report precision measurements of the nuclear magnetic moment of 43Ca+, made by microwave spectroscopy of the 4s2S1/2∣∣F=4,M=0⟩→∣∣F=3,M=1⟩ ground level hyperfine clock transition at a magnetic field of ≈146G, using a single laser-cooled ion in a Paul trap. We measure a clock-transition frequency o...

description We report precision measurements of the nuclear magnetic moment of 43Ca+, made by microwave spectroscopy of the 4s2S1/2∣∣F=4,M=0⟩→∣∣F=3,M=1⟩ ground level hyperfine clock transition at a magnetic field of ≈146G, using a single laser-cooled ion in a Paul trap. We measure a clock-transition frequency of f=3199941076.920(46)Hz from which we determine μI/μN=−1.315350(9)(1) where the uncertainty (9) arises from uncertainty in the hyperfine A constant, and the (1) arises from the uncertainty in our measurement. This measurement is not corrected for diamagnetic shielding due to the bound electrons. We make a second measurement which is less precise but agrees with the first. We use our μI value in combination with previous NMR results to extract the change in shielding constant of calcium ions due to solvation in D2O:Δσ=−0.00022(1).
