The polarization purity of 6. 457- and 12. 914-keV x rays has been improved to the level of 2. 410^-10 and 5. 710^-10. The polarizers are channel-cut silicon crystals using six 90^ reflections. Their performance and possible applications are demonstrated in the measurement of the optical activity of a sucrose solution.
Marx et al. (2013) studied this question.
