Interaction potential for the X¹Σ state of Li⁺ + Ar

The ground state potential curve of LiAr+ was calculated using the configuration interaction (CI) method. Analysis of computational errors and comparison with experimental differential cross section data yields σ = 3.66 ± 0.05 αo, Re= 4.44 ± 0.05 αo, and De = 0.30 ± 0.01 eV for the potential well parameters. © 1979.
