Photon Splitting in a Very Strong Magnetic Field
V. N. Baier, A. I. Milstein, R. Zh. Shaisultanov
Abstract
Photon splitting in a very strong magnetic field is analyzed for energy ω< 2m. The amplitude obtained on the base of operator-diagram technique is used. It is shown that in a magnetic field much higher than critical one the splitting amplitude is independent on the field. Our calculation is in a good agreement with previous results of Adler and in a strong contradiction with recent paper of Mentzel et al.
