The imaginary part of the fourth order matrix element for the electromagnetic scattering of two fermions gives rise to a small dependence of the cross section on the quantity s· p1×k1, where s and p1 are the spin and momenta of one of the initial particles, and k1 the momentum of the same particle after scattering. The resulting angular asymmetry can probably be measured. The effect does not occur in the lowest order of scattering.
