Theoretical parameters of powerful radio galaxies. III. Acceleration of particles

It is shown that particle acceleration at the fronts of strong shock waves in the hot spots and lobes of powerful radio galaxies is an effective mechanism for the generation of relativistic electrons with ..gamma../sub e/ approx. 10/sup 7/ and protons with energy approx. 10/sup 20/ eV. The efficienc...

Zusammenfassung:	It is shown that particle acceleration at the fronts of strong shock waves in the hot spots and lobes of powerful radio galaxies is an effective mechanism for the generation of relativistic electrons with ..gamma../sub e/ approx. 10/sup 7/ and protons with energy approx. 10/sup 20/ eV. The efficiency of acceleration of relativistic electrons by cyclotron resonance with Alfven turbulence behind the front of the reverse shock wave in the hot spot of a radio source is estimated.
