Abstract

Isotope energy shifts and hyperfine structure have been measured for 33 high-energy Rydberg levels of atomic xenon by sub-Doppler two-photon excitation spectroscopy, using narrowband pulses of coherent ultraviolet light at 205-213 nm generated by nonlinear-optical conversion processes. Rydberg levels are accessed at two-photon excitation energies in the 97 300-94 100 cm-1 range where isotope energy shifts and hyperfine structure have rarely been resolved; these Rydberg levels are 5p5 np [1/2]0 (n = 9-13), 5p5 np [3/2]2 (n = 9-13), 5p5 np [5/2]2 (n = 9-17), 5p5 nf [3/2]2 (n = 6-14) and 5p5 nf [5/2]2 (n = 6-10). The sub-Doppler spectra display diverse hyperfine-coupling effects, for which least-squares-fit spectroscopic parameters reflect the influence of angular momentum.
