Abstract

A possibility to measure the energy and polarization distributions of high intensity gamma-beams is considered. This possibility is based on measurements of the number of electron-pozitron pairs in such media as laser waves and single crystals. The method may be useful for future gamma-gamma and e-gamma colliders.
