Abstract

The ArH emission at 7670 Å first observed by Johns in 1970, is produced by X-ray irradiation of Ar gas mixtures with H₂, H₂O, CH₄ or CH₃OH. To assign this transition, potential curves for the Rydberg states of ArH⁺ converging to the ground state of ArH⁺ are calculated by a fast method, whereby Hartree-Fock electron affinities of ArH⁺. are added to the ArH⁺ potential. Results with and without semi-empirical correlation corrections are presented. The 7670 /rA transition is shown to be G ²Π → A ²Σ with the lower state predissociated by vibronic interaction with the continuum of the ArH around state.
