Popis:	and 2p9(J =2) states in the 5p'6p con6guration and photoionization cross sections at 193 and 248 nm from the 2p5 and 2p6 states have been determined and are compared with previous experimental and theoretical values where such exist. Fluorescence depletion spectroscopy as a method for deter- mining excited-state photoionization cross sections is described and discussed and shown to have many attractive features. Based on our cross-section measurements, we calculate that (2+ 1)-photon photoionization in Xe with a laser intensity of 30 MW/cm during 25 ns at 249.6 nm, using the 2p, (J =0) state as an intermediate state, can produce a fractional ionization of 10%.
