Photoelectron energy and angular distributions for resonantly enhanced multiphoton ionization (REMPI) of xenon via the three-photon-allowed 7s({sup 3}/{sub 2}){sup 0}{sub 1} and 5d({sup 3}/{sub 2}){sup 0}{sub 1} states have been studied both experimentally and theoretically. The electron kinetic energy spectra give the probability of leaving Xe{sup +} in either the {sup 2}P{sub 1/2} or {sup 2}P{sub 3/2} core. The measured branching ratio for leaving each ionic core is used to test the theoretical description of the REMPI process. Measurements of {ital both} the angular distribitions and the (3+1) REMPI via the 5d state are adequately reproduced by multichannel quantum defect theory. However, measurements of angular distributions for the electrons resulting from (3+1) via the 7s({sup 3}/{sub 2}){sup 0}{sub 1} state into Xe{sup +2}P{sub 3/2} (core preserving) or Xe{sup +} {sup 2}P{sub 1/2} (core changing) are in striking disagreement with theory.
