Abstract
Presented is the first experimental demonstration of a dramatic radiat ive redistribution in transverse states for multi-GeV electrons/positr ons, interacting with strong crystalline fields. Detailed analysis of energy loss, photon multiplicities, and scattering distributions leads to new physical insight into open questions such as radiative cooling /heating of the beams in aligned crystals, validity of the constant-fi eld approximation, radiative capture of random particles (''feed in'') into channeled states, and the Landau-Pomeranchuk effect in multiphot on radiation spectra.
