Unusual properties of some E= 0 localized states and the quantum-classical correspondence

AJ Makowski, KJ Gorska - Physics Letters A, 2007 - Elsevier
For zero energy, E= 0, we propose some states which are perfectly well localized on the
classical solutions for all the central power-law potentials V (r)=− γν/rν, with γν> 0, and ν<− 2 …
