- The atomic-beam magnetic-resonance method with separated oscillatory fields was used to measure the hyperfine structure separation and magnetic dipole moment of the isotopes Rb<sup>85 </sup> and Rb<sup>86</sup>. Observation of a Δ F = plus or minus 1 doublet in the magnetic field region where its mean value is a minimum gives the values of these observables; the doublet separation is proportional to the nuclear g factor and the mean doublet frequency is proportional to the hyperfine structure separation. Results obtained on Rb<sup>85</sup> are in excellent agreement with previously published values, and indicate that the transition frequencies calculated from the Breit-Rabi energy-level equation agree with the experiment to better than one pant per million. For the isotope Rb<sup>86</sup> the following values were obtained for the <sup>2</sup>S<sub>1/2</sub> electronic ground state: Δ ν = 3946.883(2) Mc, g<sub>l</sub>=--4.590(4) x 10<sup>-4</sup>, μ<sub>l</sub> = --1.6856(14)nm. The hyperfine structure anomaly was found to be. Δ = 0.17(9)%. Details of the apparatus constructed for the purpcse of measuring these anomalies in radioactive alkali isotopes are presented, as well as the comparison of the experimental result with values predicted for the anomaly by using various nuclear models and the Bohr-Weisskopf theory.
