Photoelectron energy and angular distributions are reported for resonantly enhanced multiphoton ionization (REMPI) through the three-photon-allowed 6s(3/2)/sup 0//sub 1/ and 6s'(1/2)/sup 0//sub 1/ states of xenon at laser-power densities of --10/sup 9/-10/sup 11/ W/cm/sup 2/. Ionization from three-photon resonance with the 6s(3/2)/sup 0//sub 1/ state gives two photoelectron peaks corresponding to leaving the ion in either the /sup 2/P/sub 3/2/ or the /sup 2/P/sub 1/2/ state. It is found that the two groups of photoelectrons have distinctly different angular distributions. Calculations indicate that configuration mixing in the 6s manifold is important in describing the observed angular distributions. REMPI via the 6s'(1/2)/sup 0//sub 1/ state gives one main photoelectron peak resulting from autoionization to the /sup 2/P/sub 3/2/ state of the ion. Two additional peaks of higher-energy photoelectrons are seen, which are due to absorption of an additional photon before ionization. Strong core-changing processes are evident in the spectra.
