Abstract
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.
