Generalized Eigenfunction Expansion Near Resonances
(54K, TeX)

ABSTRACT.  The non-relativistic quantum mechanical description
of meta-stable states which arise by perturbation of
embedded eigenvalues is considered. A model is
studied which is exactly solvable in the sense that
the continuum eigenfunctions for the perturbed
system can be found. Systematic approximations for
these eigenfunctions are obtained. These approx-
imations have a particularly simple form near the
resonances.
