Abstract Very accurate measurements of then 2 S 1/2 (n=9–30),n 2 P 1/2,3/2 (n=9–50) andn 2 D 3/2, 5/2 (n=5, 8–32) energy levels in Cs I have been performed in the wavelength-range 6,379 Å〈λ〈7,432 Å with a high-precision vacuum-wavemeter using either Doppler-free two-photon spectroscopy or Doppler-limited one-photon spectroscopy with a frequency-doubling crystal. Thermionic detectors were used throughout the experiments. By fitting the experimental energy values to extended Rydberg-Ritz formulas, accurate quantum defect data and series limits are given. The ionization energyE i =31,406.4710(7) cm−1 was adopted to be the best fit value, differing significantly from most recent evaluations of other authors, but agreeing well with former, less accurate measurements performed in our laboratory.
