We examine very high energy Compton scattering on bound electrons, comparing cross sections obtained using relativistic impulse approximation (RIA) to the extreme relativistic (ER) limit of the exact Coulomb (EC) results for the 1selectron. For this purpose, in the case of an initial bound sstate, we establish analytic expressions, valid within RIA, for the triply differential cross section (TDCS), corresponding to the detection of photons...
