Abstract
We derive the cross-section for one-quantum annihilation of polarized elect rons and positrons. The electron and positron can occupy arbitrary Landau l evels and have non-zero momentum parallel to the field, and the cross-secti on is calculated for any polarization of the radiation. When we take zero p arallel momentum for the electron and sum over photon polarization we obtai n results which agree with the existing calculation of Wunner et al. (1986) .
