A simple formula for the thermal pair annihilation line emissivity.
SVENSSON R., LARSSON S. and POUTANEN J.
Abstract (from CDS):
We introduce a simple and convenient fitting formula for the thermal annihilation line from pair plasmas in cosmic sources. The fitting formula is accurate to 0.04% and is valid at all photon energies and temperatures of interest. The commonly used Gaussian line profile is not a good approximation for broader lines.
