Abstract
It is shown that the exchange of an odd number of photons in laser-assisted charge-particle scattering is forbidden when the laser polarization is perpendicular to the scattering plane. It is proposed that this selection rule may be used to test the satisfaction of single-collision conditions under critical geometrical conditions where experimental count rates tend to become prohibitively small.
