Abstract

We compute non-relativistic ab initio electronic potential surfaces for two-metastable 2p53s neon atoms using a multiconfiguration all-electron valence-bond method. Spectroscopic constants and long-range C6 dispersion coefficients are presented for 3,5ςg/u, 3,5IIg/u, 1,3,5δg/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.
