| Abstract: | High-resolution optical spectroscopy of Rb atoms in an intermediate-Zeeman magnetic field regime is performed. Magnetic fields between 0.05 T and 0.13 T are measured. We introduce a measurement approach based on three-level Λ systems where the open-loop frequency energy separation is determined by the applied magnetic field. Using this method an accuracy better than 100 ppm is reached in a measurement series. In parallel, on the basis of complementary measurements based on three-level V systems we obtain the first experimental value of the Landé g-factor of the first excited state for 85 Rb, 85 g J (5 P 1 / 2) =0.66709(7), and for 87 Rb, 87 g J (5 P 1 / 2) =0.6663(2). Our approach is unprecedented in the literature for Rb. Experimental results for the Land´e g-factor of the first excited state of Rb [ABSTRACT FROM AUTHOR] |
