title = "The twilight zone in the over-barrier scattering: Between perturbation theory and quasiclassics",
abstract = "We discuss the applicability of Born (small perturbation) and WKB (quasiclassical) approximations for one-dimensional over-barrier scattering problem with weak long-range potentials of different profiles, both deterministic and random. The dependence of the reflection coefficient R and the localization length lloc on the amplitude and variation scale of the scattering potential is studied. It is shown that the perturbation and quasiclassical approaches are inconsistent with each other. The quantities R and lloc are quite individual for each given potential and an explicit universal condition restricting the applicability of both methods does not exist.",
