Klein-Nishina Effects on Optically Thin Synchrotron and Synchrotron Self-Compton Spectrum [PDF]

, 2009
We present analytic approximations to the optically thin synchrotron and synchrotron self-Compton (SSC) spectra when Klein-Nishina (KN) effects are important and pair production and external radiation fields can be neglected.
