Ab. Apyan et al., CRYSTAL ALIGNMENT AND MEASUREMENT OF PHOTON POLARIZATION USING COHERENT E(-) PHOTOPRODUCTION AT ENERGIES ABOVE 50 GEV()E(), Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 115(1-4), 1996, pp. 384-386
The dependence of the total absorption coefficients for polarized phot
ons on the energy and orientation angles is calculated. The results sh
ow that the asymmetry of pair production can be used for crystal align
ing and measuring the photon energy.
