Electronic structure and fluorescence spectrum of the HeO+ cation

Abstract

Quantum-mechanical calculations of the potential curves of the HeO+ ion are preformed which correlate with four lower dissociation limits and indicate the excimer type of the ion. The transition dipole moments of the 22Σ−→12Σ− and 24Σ−→14Σ − transitions are calculated. The energies and radiative lifetimes of vibrational levels are determined and structural and spectroscopic constants of the states 12Σ−, 22Σ−, 14Σ−, and 24Σ− are calculated. The fluorescence spectrum corresponding to the 22Σ−→12Σ− and 24Σ−→14Σ − transitions is also calculated. The possibility of lasing at these transitions is discussed.
