Abstract
We recalculate the amplitude for photon splitting in a strong magnetic field below the pair production threshold, using the world line path integral variant of the Bern-Kosower formalism. Numerical comparison ( using programs that we have made available for public access on the In ternet) shows that the results of the recalculation are identical to t he earlier calculations of Adler and later of Stoneham and to the rece nt recalculation by Baler, Milstein, and Shaisultanov.
