The two-photon resonant, three-photon ionization spectrum of Xe₂ determined in the wavelength region of Xe* 5d and 6p states shows a number of molecular band systems that display discrete vibronic structure. Photoelectron spectra determined via five of these band systems provide new information on the dissociation energies of the dimer ion states that dissociate to Xe¹S₀+Xe⁺ ²P⁰_3/2 or ²P⁰_1/2. In particular, the present photoelectron spectra provide the first observation of the weakly bound Xe₂ ⁺C²II_3/2u and D²σ_1/2g⁺. In addition, it is shown that, by judicious choice of the resonant intermediate state, it is possible to probe the potential energy curves of the ionic states in regions that are not accessible from the ground state due to poor Franck-Condon overlap.
