That the bound energy eigenstates of one-dimensional quantum systems can be degenerate in the presence of specific singular or supersingular potentials is demonstrated by choosing a family of bistable and other oscillators. Relevance of our study to spectroscopic observations is noted. Quasi-degener

β¦ Synopsis
In this paper, we consider the inverse scattering problem for the SchrΓΆdinger equation in two dimensions. This problem of reconstructing the scattering potential from the far field data has a well-known approximate solution based on the linearization through the weak scatterer (or Born) approximation. In the present work it is shown that while this approximate solution need not be close to the underlying scattering potential, the leading local singularities of the potential are recovered exactly in this procedure. 1994 Academic Press, Inc.

The Schrodinger equation for the scattering of an electron by a hydrogen molecule is solved by the finite element method, in spherical coordinates, using fifth-order Hermite interpolating polynomials. The computational method is quite similar to the w Ε½ . x work of Shertzer and Botero Phys. Rev. A
We consider the problem of determining a radially symmetric potential in the three-dimensional SchrΓΆdinger equation from eigenvalues associated with two different angular-momentum quantum numbers. This leads to a singular eigenvalue problem for which there are no known general uniqueness results for
