Abstract

It is shown that the approximation scheme to the Schrödinger equation with purely outgoing asymptotics based on the separable expansion of the potential (PSE method) can be extended into the wave-number region k = κ-iγ with 0 <γ <κ. This extended scheme is proved to be equivalent to the analytic continuation of the homogeneous Lippmann-Schwinger equation into the same region. Thus its solutions are the Gamow states. As the PSE method handles spherical and non-spherical potentials on an equal footing it is able to yield Gamow states in deformed potentials.
