    "abstract": "While Klein paradox is often encountered in the context of scattering of\nrelativistic particles at a potential barrier, we presently discuss a puzzling\nsituation that arises with the Klein-Gordon equation for bound states. With the\nusual minimal coupling procedure of introducing the interaction potential, a\nparadoxical situation arises when the \u0027hill\u0027 becomes a \u0027well\u0027, simulating a\nbound-state like situation. The phenomenal phenomenon for bound states is\ncontrary to the conventional wisdom of quantum mechanics and is analogous to\nthe well-known Klein paradox, a generic property of relativistic wave\nequations.\n  PACs Nos. 03.65.Ge, 03.65.Pm",
