The Pair Production Spectrum from Photon-Photon Annihilation
arXiv:astro-ph/9703069
Abstract
We present the first completely analytical computation of the full differential γ-γpair production rate from compact radiation fields, exact to 2nd order QED, and use this result to investigate the validity of previously known approximations.
