CHERENKOV RADIATION OF E(-) PAIRS AND ITS APPLICATION FOR THE MEASUREMENT OF GAMMA-QUANTA BEAM POLARIZATION()E()

The dependence of the Cherenkov radiation intensity of e(+)e(-) pairs produced by high-energy gamma-quanta on the distance z from the pair p roduction point, the radiator thickness L, and the azimuthal angle phi of the observation point from the gamma-quanta linear polarization di rection is calculated, taking into account the multiple scattering. It is shown that the measurement of the gamma-quanta polarization by det ection of the expected phi-asymmetry with the help of a RICH detector is easier than with other existing or proposed methods.
