Abstract

In this contribution the case is made that relativistic protons as predicted by diffusive shock acceleration can lead to X-ray emission exceeding synchrotron-self-Compton emission by electrons accelerated by the same process. Photomeson cooling of protons on ambient soft synchrotron photons of the primary electrons initiates a three-generation cascade of secondary particles terminating at X- to soft γ-ray energies. Pure nonthermal sources like hot spots in Fanarov-Riley type 2 (FR II) galaxies or similar objects are proposed as optimum candidates to confirm predicted convex spectra with an effective spectral index α x = 0.7 +0.2−0.1 in the ROSAT-band and a luminosity ratio L κeV/L <1eV ≈ 1%.
