Abstract
A comparison is made, for various two-photon processes (ee → eeπ0, eeµ+ µ-, eeπ+ π-), between an exact calculation on the one hand and two alternative forms of the equivalent photon approximation (namely, the Low formula and the Dalitz-Yennie formula) on the other hand. Angular distributions of the particles produced are considered, as well as total cross sections.
