Calculations are presented of beam polarization-dependent effects in high energy e+ e- storage rings. The elastic scattering within a circulating bunch (Touschek scattering) leads to a net polarization-dependent effect of 5 to 10% for parameters appropriate to SPEAR. The final state angular distributions of the scattering processes studied are considerably modified by beam polarization, even for relatively low values of the time-averaged polarization. Calculations of counting rates and polarization-dependent effects for these e+e- collision processes are given.
