Abstract: (arXiv)
An approximation for the inverse-Compton radiation power of electrons in the isotropic black-body photon field is presented. The approximation allows one to calculate inverse-Compton emissivity as integral over the energies of incident electrons rather than over the field photon energies. Such an approach opens the possibility for accurate modeling of IC emission of electrons with energy spectra being different from power-law, in tasks where powerful CPU resources are essential. High accuracy of this approximation allows one to use it in a wide range of conditions, from Thomson to extreme Klein-Nishina limits.
