In view of extending the shell model to highly deformed states of heavy nuclei, we discuss the evaluation of the Green's function for the Schrodinger equation in three dimensions with a smooth potential, in the limit of large quantum numbers. Such an evaluation is possible only after smoothing over
to continue the result to the real axis. Numerical analytic continuation, however, is notoriously difficult, and most The need to calculate the spectral properties of a Hermitian operator H frequently arises in the technical sciences. A common ap-techniques developed thus far are useful only for sp
