ON THE LONGITUDINAL DEPOLARIZATION OF BEAMS OF SPIN 1/2 PARTICLES BY MULTIPLE COULOMB SCATTERING
S>The average longitudinal depolarization of an electron beam by multiple Coulomb scattering was evaluated. The treatment is hased on the iteration, extended to a whole succession of scatterings, of the matnix which describes the variation of the polarization atate for a single scattering, and on the average of the iterated matrix on all possible scattering successions. A very simple formula was obtained for the average longitudinal polanization degree of the whole outgoing beam, and the final expressions were evaluated by using the second Bonn approximation. Numerical values of the depolarization for aluminum and gold targts and for several values of energy and thickness are given; these values in all cases considered were never greater than a few per cent.
