We compute nonrelativistic ab initio electronic potential surfaces for two metastable 2p 5 3s neon atoms using a multiconfiguration all-electron valence-bond method. Spectroscopic constants and long-range C 6 dispersion coefficients are presented for 3,5 Σ g/u , 3,5 Π g/u , and 1,3,5 Δ g/u symmetries. In addition, we analyze the role of various atomic configurations in the formation of the neon dimer. Our results can be used to model the suppression of collision-induced ionization of metastable neon, which is believed to be a good candidate for Bose-Einstein condensation.
