Hi Angel,
I think that such patterns will be of little help to you. If you have a
perfect Si crystal then double diffraction may appear and forbidden
reflections can be seen. Yesterday we discussed with my collegue his
diffraction experiments with Si crystal cut along (100). He said that he
clearly see forbidden (200) reflection, which appears and disappears when
sample rotation is on.
Anyway, even if you will be able to find such patterns you cannot use them
for determination of line position because line shift and broadenong in
asymmetric geometry both depends on grazing angle (c.f. H. Toraya, J.
Yoshino, J. Appl. Cryst 27 (1994) 961).
Hope this helps.
Kind regards,
Eduard.

Subject: grazing angle diffraction in single-crystal Si
Dear All:
How knows references where I could find the entire diffraction pattern of
single-crystal Si taken under grazing angle diffraction.
Thanks so much,
Angel L. Ortiz
