Maximally resonant potentials subject to p-norm constraints

Roman Svirsky

Vol. 129 (1987), No. 2, 357–374
Abstract

We prove the existence of and characterize quantum-mechanical potentials within certain Lp-classes that produce maximally sharp resonances. The best results are obtained in the spherically symmetric case where it is shown that, roughly speaking, maximally sharp resonances are caused by barrier confinement of a metastable state, although in some cases there is interaction in the interior of the confining barrier.
