Abstract
The x-ray polarization ratios of graphite monochromator
are obtained by measuring its u- and n-component of the x-ray
after reflection from the monochromator. Both the u and rr
polarizations are measured by x-ray anomalous transmission of
perfect crystal. The results are 0.910(3) for Cu K, and 0.952(10)
for MO K,, radiation. The diffraction data of Cu K, and MO K,
radiations show that the polarization status has a tendancy of
moving away from an ideally perfect crystal value to mosaic crystal
value as the wavelength of the radiation becomes shorter.
