These conditions yield a monotonic series of lower limits on the \"critical\" value of the strength of the potential (for which a first bound state appears) which converges to the exact critical strength. We also obtain a sufficient condition for the existence of bound states in a central monotonic potential which yield an upper limit on the critical strength of the potential.", "revisions": [ { "version": "v1", "updated": "2004-01-12T11:40:10.000Z" } ], "analyses": { "keywords": [ "sufficient condition", "first bound state appears", "nonrelativistic quantum mechanics", "central monotonic potential", "arbitrary central potentials" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable" } } }
