On Polarization Of The Beam Extracted With The Bent Crystal

Particles scattered off the nuclear target acquire a polarization if the nuclei have a non zero analyzing power. This effect is enhanced when particles traverse a bent crystal. Such enhancement under certain assumptions allows one to measure the analyzing power at the level of 10^-4 at the square of transfer momentum |t| < 10^-5 (GeV/c)2. If it happens that the analyzing power is big enough, then one can get the beam polarization more than 50% after extraction of the primary beam with the bent crystal.
