A fast beam of sulfur Rydberg atoms is formed by charge exchange from an 11-keV beam of S[sup +] ions in a crossed thermal rubidium beam, laser-excited to the 10[ital F] or 8[ital F] levels. Population of specific [ital n]=9,10 sulfur Rydberg levels is studied by selective excitation with a Doppler-tuned CO[sub 2] laser followed by field ionization. Complete spectral resolution of levels with [ital L][ge]4 allows a direct study of the populations in specific [ital nL] levels and reveals distinctly nonstatistical distributions of population in [ital L]. The results are compared with predictions of a classical Monte Carlo three-body collision theory, revealing some similarities, but also clear differences.
