Abstract

The recently introduced scheme 20,21 is extended to propose an algebraic non-perturbative approach for the analytical treatment of Schrödinger equations with non-solvable potentials involving an exactly solvable potential form together with an additional piece. As an illustration the procedure is successfully applied to the Cornell potential by means of very simple algebraic manipulations. However, instead of providing numerical eigenvalues for the only consideration of the small strength of the related linear potential as in the previous reports, the present model puts forward a clean route to interpret related experimental or precise numerical results involving wide range of the linear potential strengths. We hope this new technique will shed some light on the questions concerning with the limitations of the traditional perturbation techniques.
