Characteristics of parametric X-ray radiation (PXR) from polarized charged
fermions based on the quantum theory have been investigated. Spin-dependent
part of PXR cross-section on spin of the incident particle has been obtain
ed near the K-edge of crystal target. Estimation of coefficient of PXR proc
ess asymmetry was made. The comparison with quantum effects in transition r
adiation has been carried out. (C) 2001 Elsevier Science B.V. All rights re
