The Manning–Rosen potential using J-matrix approach

Abstract

Close to the bound-resonance crossover region, state energies for the Manning–Rosen (MR) potential have been calculated. New data, for both bound and resonance state energies have been reported nearby the crossover region, using the J-matrix approach, for LiH and CO molecules. Furthermore, the average oscillator strength, multipole moments and transition probabilities for certain states have been reported for future comparison.
