The solutions of the phase equation for a potential with the asymptotic properties of an atomic polarization potential are studied with the intention of developing a computer program for direct integration of the phase equation for the s-wave phase shift of an arbitrary potential. Such a program is developed and its limitations are discussed. In addition, an appendix is devoted to the variational principles of Kohn and Schwinger for calculating phase shifts.
