Five-photon ionization spectrum of atomic Xe in the region between the Xe+
2Po3/2 and 2Po1/2 limits is reported. Using linearly polarized light, three
autoionizing series are observed converging to the Xe+ 2Po1/2. Photoelectron
energy distributions corresponding to the three-autoionizing series were
recorded.
