Abstract
A variational method is constructed for the Feshbach equations for scattering. An example is carried out on the -wave electron-hydrogen system. It is shown that fast convergence of the phase shift can be obtained throughout the energy range of interest including the resonance region. No anomalous singularities have been encountered.
