CI Potentials for the X ²Σ and a ²Π states of Ar⁺ + He

Configuration interaction (CI) potentials have been calculated for the ground X 2Σ and A 2Π molecular states of Ar+ + He. Both potentials are found to be weakly bound with the potential well characteristics for the X 2Σ state, Re = 4.71 a0 and De = 55.0 meV, and for the A 2Π state, Re = 5.65 a0 and De = 26.2 meV. © 1978.
