Measurements of gJ ratios for Rb85, Rb87, hydrogen, and deuterium, and of the hyperfine separation of deuterium

Journal Article

An optical pumping technique has been used to measure atomic g-factor ratios among Rb85, Rb87, hydrogen, and deuterium, and the ground-state hyperfine separation in deuterium. An evacuated wall-coated optical absorption cell was employed for its advantages of a narrow and symmetric magnetic-resonance line shape. Measurements were carried out at applied magnetic fields of 7.6 and 14.5 G, and with both senses of circular polarization of the Rb pumping light. The Rb gJ ratios quoted are the averages of measurements for both Rb85 and Rb87 at both magnetic fields and both senses of circular polarization of the Rb pumping light, and the "extreme mF" Zeeman transitions yielding the strongest Rb optical pumping signals were the ones measured with a given polarization sense. The results were gJ(Rb85,87)gJ(H)=1+(23.60.4)×10-6, and gJ(Rb85,87)gJ(D)=1+(23.50.3)×10-6. Comparing gJ(Rb)gJ(H) and gJ(Rb)gJ(D) measurements for specific Rb transitions yielded the ratio gJ(D)gJ(H)=1+(0.10.2) ×10-6. The result for the measurement of the deuterium hyperfine separation was (D)=327 384 352.61.2 cps. © 1968 The American Physical Society.
