The paper presents a variational method for calculating elastic s-wave scattering phases for short-range potentials, based on the Rayleigh-Ritz method for discrete energy levels, in which the approximate phase approaches the exact phase from below. The method is applied to scattering of electrons by the static field of the hydrogen atom.
