Abstract

A special class of separable potentials in the momentum space is proposed which is equivalent to 3D δ-functions in the configuration space. These potentials allow generation of a large number of exact solutions of time-dependent and time-independent Helmgoltz (Schroedinger) equations. It is shown numerically that in the 1D case δ-functions effectively approach the continuous potentials via a convergent algorithm.
