A Simple Three-Parameter Model Potential For Diatomic Systems: From Weakly and Strongly Bound Molecules to Metastable Molecular Ions

Rui-Hua Xie, Jiangbin Gong

Based on a simplest molecular orbital theory of H${}_2^{+}$, a three-parameter model potential function is proposed to describe ground-state diatomic systems with closed-shell and/…
