Scientific paper

The authors calculate the efficiency of production of positrons by γ-γ interaction under conditions which may occur in the Galactic center. Their annihilation line and three-photon annihilation continuum contribute to the emitted radiation. If a geometrical model is assumed, it will be possible to determine the parameters of the γ-ray source region. By comparing the computed spectra to observations a rough estimate is made using extant data.
