A new, direct vacuum-ultraviolet laser-excitation method is used to study the single-photon autoionization of xenon atoms in the 5p6→5p5 ns′[1/2]10 (14≤n≤52) and 5p6→5p5 nd′[3/2]10 (16≤n≤78) autoionizing Rydberg series. Fano profile parameters for both series are reported over the entire range of observed states. From analysis of the nd′ series an ionization potential Td=108 370.82±0.05 cm−1 is obtained. This agrees well with a previously reported limit of 108 370.8±0.2 cm−1.
