The asymmetry of parametric x rays emitted by polarized electrons is consid
ered on tile basis of quantum theory. The asymmetry value is calculated for
emission both in the Bragg direction and in directions different from the
Bragg direction hy ari angle of order gamma (-1). The asymmetry is computed
for the longitudinal and for the transverse polarization of the electrons.
