ABSTRACT

The problem of single Compton scattering is considered and the resulting spectrum, angular distribution and polarization of scattered photons in a general case are obtained. The inverse Compton scattering (ICS) for arbitrary energies of electronsE and photons ω0 is investigated in detail. In the case of isotropically-distributed initial photons and relativistic electrons, a strong rise of the scattered spectrum near the upper edge takes place, starting from the values of the characteristic parameterb≡4Eω0≳10 (in units of mc2=1). The energy-loss rate of relativistic electrons due to ICS is calculated. It is shown that the relativistic electrons of the energiesE≳100 MeV, when scattering on the X-rays with ω0~10KeV, transmit the dominant part of their energy to the photons which fall after scattering into the energy range of the electrons (≳100 MeV).The radiation spectrum of ICS, as well as the energy-losses of relativistic electrons distributed by power-lawE−α, are calculated. The radiation spectrum reveals the power-law behaviour with the different indices in two limits: the dependence ω−(αα1)/2 at ωω0≪1 gradually changes to ω−(α+1) ln (ωω0) law for ωω0≫1. More... »
