Abstract

Angular and energy distributions of electrons and positrons created by 83–133 GeV photons in an aligned crystal (strong field pair creation) have been measured. The experiment exhibits the “blocking” effect for the positron and the difference of energy loss between channeled electron and quasi-channeled positron. The data are well reproduced by a Monte Carlo simulation.
