Coupled-electron-pair approximation calculations on open-shell molecules: The two lowest states of HeNe+

Description

Extensive ab initio calculations at coupled-electron-pair approximation and multireference configuration interaction levels have been performed for the two lowest states X 2Σ+ and A2Pi of HeNe+. Spin-orbit coupling has been included on a semiempirical basis in order to account for the strong mixing between the X 2Σ/sub 1/2/+ and A22Pi/sub 1/2/ components, which influences the properties of both these states in the experimentally observed region at large internuclear distances
