MILLIMETER-WAVE SPECTROSCOPY OF CESIUM RYDBERG STATES AND POSSIBLE APPLICATIONS TO FREQUENCY METROLOGY

J. Raimond , P. Goy , G. Vitrant , S. Haroche

An extensive high-resolution study of the millimeter-wave spectrum of Cesium Rydberg states is presented, yielding new precise values of the nS, nP, nD and nF states quantum defects (23 ⩽ n ⩽ 45), and of their fine and hyperfine structures. The quantum defects values allow us to predict the frequency of any n,ℓ → n',ℓ' (n ⩾ 20, ℓ ⩽ 3) transition, with a MHz accuracy. This precise mapping of the Cesium Rydberg states can provide a new secondary frequency standard in the 50 GHz - 10 THz range. Possible interesting metrological applications are discussed.
