Notes:
Using a double crystal diffractometer with an additional crystal between the two crystals used as X-ray-optical polarizer and analyzer the phase relation between mutually perpendicularly polarized wave fields is examined in the Bragg case. The additional crystal is a (110)-surface oriented silicon crystal adjusted for the symmetric 220 Cu Kα1 Bragg case. In the case of coherent excitation of both σ- and π-polarized wave fields in the silicon crystal it is experimentally shown that a unique phase relation exists. In a further experiment it is demonstrated that in the case of incoherent excitation the rocking curve is the sum of the σ- and π-polarized intensities without any phase relation. Owing to the different half width of these two curves, step-shaped flanks of the rocking curve are found at excitation with unpolarized radiation.
