Determination of g-factor ratios for free Cs133 and Rb87 atoms
The ratio of the nuclear g factor to the electronic g factor in the ground electronic state of free Cs133 atoms and the ratio of the electronic g factors of Cs133 and Rb87 atoms have been determined using optical-pumping techniques in a magnetic field ≤50 G. The results are gIgJ(Cs133)=-1.9917400×10-4×(1±1.3×10-6); gJ(Cs133)gJ(Rb87)=1.0001044737×(1±4.4×10-9). Using these values together with results of other researches yields gI(Csaq+)gI(Cs)=1+(344.0±1.5)×10-6, the ratio of the nuclear g factor of the Cs ion in aqueous solution to that of the free Cs atom. Finally, the value for the shielded Cs nuclear moment in units of the Bohr magneton is found to be gI(Cs133)=-0.39885395×(1±1.3×10-6)×10-3. © 1973 The American Physical Society.
