Photodissociation in Strong Magnetic Fields and Application to Pulsars
Abstract
The cross sections for the photoionization of positronia in strong magnetic fields are derived within the Born approximation. Further, the total ionization rate of the positronium by thermal photons in strong magnetic fields is computed. The application of this process is discussed 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.
