Hi. The XRD profile (spectrum) does not only depend on the geometry type, but also width of both slits (primary divergence and secondary anti-scatter), symmetric (the same at the primary and secondary part) or non-symmetric solers, the use of any additional optical elements (e.g., we use radial soler instead of the secondary slit), type of detector (the "detector slit" of the zero-dimensional detector does not have the same physical meaning as the corresponding window of the position-sensitive detector). You cannot hold the B-B geometry in the reflection mode when you go to transmission mode - that is why the second one is used to observe reflections that are not seen (or barely seen) in the previous mode. Peak shape, including its width, would - in some cases - also be different, but peak intensity would especially be affected (in many cases).
I would use LaB6 and silicon standards (of NIST SRM) instead of corrections to check the geometry. I'm not an expert in terms of grazing incidence, but I'm pretty sure that is gives much different information, as this is more textural information. > Dear Rietvelders > > > > Does analysis done in Bragg Brentano geometry holds for other geometries > and XRD techniques providing one have diffracted peaks? > > Are there corrections needed to apply between methods. > > Say Sheher formula.
