Abstract
We analyze the splitting of a photon with energy omega below the e(+)e (-) pair-production threshold in an ultrastrong magnetic field. We use the amplitudes found by employing the operator diagrammatic technique . In a field considerably above the critical values the process amplit udes become independent of the field strength. A study of the polariza tion operator of a photon in an external field of arbitrary strength i n the energy range considered in the present investigation shows that there is only one set of polarizations of the initial and final photon s for which the splitting amplitude is nonzero.
