We show that the complex eigenenergies obtained for the latter tend either to those of the former, or to real rational numbers as $\\lambda \\rightarrow \\infty$. In the light of these results, we explain the wrong resonance energies obtained in a previous application of the Riccati-Pad\\'e method to the Schr\\\"odinger equation with a repulsive exponential potential, and further study the convergence properties of this approach.", "revisions": [ { "version": "v1", "updated": "2023-09-12T21:10:02.000Z" } ], "analyses": { "keywords": [ "schrödinger equation", "complex solution", "repulsive exponential potential", "wrong resonance energies", "real rational numbers" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable" } } }
