Strict Relationship: Potential - energy levels

Original · EN

We have developed a new simple method to build the exact analytical expression of the eigenenergy as a function of the potential. The idea of our method is mainly based on the partitioning of the potential curve, solving the Schrödinger equation, realizing a discrete form of the energy quantification condition, and finally, deriving its integral form which permit to create a simple relation: Energy-potential. Our method has been applied to three examples: the well-known square well, the harmonic oscillators, and the Morse potential. Our non numerical method is more realistic, simpler, with high degree of accuracy, both satisfactory and not computationally complicated, and applicable for any forms of potential. Our results agree very well with the preceding ones.
