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 0 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 4E
0 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 0~10KeV, 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
– , are calculated. The radiation spectrum reveals the power-law behaviour with the different indices in two limits: the dependence –(![agr](/content/t125675t05655424/xxlarge945.gif) 1)/2 at ![ohgr](/content/t125675t05655424/xxlarge969.gif) 0 1 gradually changes to –( +1) ln (![ohgr](/content/t125675t05655424/xxlarge969.gif) 0) law for ![ohgr](/content/t125675t05655424/xxlarge969.gif) 0 1. |
