Path Integral Treatment of a Linear Combination of Deformed Diatomic Molecule Potentials

The approximate bound state solutions of Schrödinger equation with linear combination of a four-parameter diatomic potential plus inversely quadratic Yukawa potential were obtained with the help of appropriate approximation to evaluate the centrifugal term. The Feynman path integral approach was used to obtain the analytical solutions. The energy spectrum and the normalized wave functions of the bound states are derived from the poles of the Green’s function and its residues. Particular cases of these potentials are also discussed briey and it is found that obtained results are in good agreement with those obtained in the literature.
