A complete set of accurate ab initio data is produced for the low-lying electronic states of Xe2+ using a coupled cluster approach (RHF-RCCSD-T), accurate relativistic effective core potentials and an extended basis set. This set of data can be useful for spectroscopical studies and for modeling of the dynamics of Xe_n+ clusters. The spin-orbit coupling is included through a semiempirical treatment. The spectroscopic constants are in very good agreement with experimental results.
