Vv. Tikhomirov, POSSIBILITY OF OBSERVING RADIATIVE SELF-POLARIZATION AND THE PRODUCTION OF POLARIZED E- PAIRS IN CRYSTALS AT ACCESSIBLE ENERGIES(E), JETP letters, 58(3), 1993, pp. 166-170
If e+/-'s and gamma rays are incident on curved crystals at small angl
es from crystallographic axes, and if the e+/-'s move under planar cha
nneling conditions, it is possible to observe a radiative self-polariz
ation and the production of polarized e+e- pairs by gamma rays at acce
ssible e+/- and gamma-ray energies.
