Abstract

The differential cross sections for polarized electron-positron scattering are calculated to order ${e}^{6}$ by using the five invariant amplitudes presented in a previous paper. The unpolarized result of Polovin is rederived. As an application of the helicity amplitudes the spin-momentum correlation for a polarized target positron is obtained in agreement with Fronsdal and Jaksic.
