Abstract
The process of photon splitting in a strong magnetic field is investigated both below and above the pair creation threshold. Contrary to the statement by Baier et al., the ``allowed'' channel is shown not to be a comprehensive description of splitting in the strong field because the ``forbidden'' channel is also essential. The partial amplitudes and the splitting probabilities are calculated taking account of the photon dispersion and large radiative corrections near the resonance.
