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