Model-Potential Calculations on the Molecular System NaNe

Calculations for the X²Σ, A²Π, and B²Σ states of the NaNe molecular system are reported. The electron-neon interaction is represented by a local potential together with an explicit orthogonality condition to the neon orbitals. The well depth and location are $D=7.8$ cm^-1 at rₘ=10 a.u. for the X²Σ state and $D=132$ cm^-1 at rₘ=5 a.u. for the A²Π state, in excellent agreement with the laser-spectroscopy results of Ahmad-Bitar et al.
