摘要：

A Kratzer-Fues potential is coupled with its self to form a double Kratzer-Fues potential. The solutions of the radial Schrodinger equation with the combined potential are obtained via two different methodologies. Using the supersymmetric approach, the energy equation for a non-approximated centrifugal term is obtained. The energy equation for the approximated centrifugal term is obtained using the parametric Nikiforov-Uvarov method. Numerical results are computed for five molecules using MATLAB software program. The computed numerical values are compared with the experimental values and the ground state energy obtained from Herzberg's energy level equation. The study revealed that the results of the approximated centrifugal term are better than the results of the non-approximated centrifugal term for four molecules.
