摘要：

The cross sections for the photoionization of positronia in strong magnetic fields are derived within the Born approximation (B approximately 10(12)-10(13) G, omega(B) = eB/m(e)c > omega', the frequency of the photon in the positronium rest frame). Further, the total ionization rate of the positronium by thermal photons in strong magnetic fields is computed. We discuss the application of this process in light of the recent suggestions that in the vicinity of the pulsars the high-energy photons can be captured by the strong magnetic fields and be transformed into bound positronia.
