Photon Splitting in a Very Strong Magnetic Field

Abstract
Photon splitting in a very strong magnetic field is analyzed for energy ω<2m. The amplitude obtained on the base of the operator-diagram technique is used. It is shown that in a magnetic field much higher than a critical one the splitting amplitude is independent of the field. Our calculation is in good agreement with previous results of Adler and in strong contradiction with a recent paper by Mentzel et al.
