Polarized inelastic electromagnetic processes in crystals with allowance for a new real distribution of nucleus charges and atomic electrons

The process of polarized electron-positron pair photoproduction via a polarized γ quantum in a crystalline medium is investigated using a new method that considers the distribution of nucleus charges and atomic electrons. Real changes in the cross sections of both polarized and nonpolarized electron pair production, and in the degrees of particle polarization in silicon crystal, are obtained.
