Dear Shay, Does your diffractometer have a Ni foil filter (to cut K-beta radiation)? The absorption edge of Ni often results in this “step” near any strong diffraction peak; it is quite normal for such arrangements.

My question is what is the origin of the step-like profile next to a very large reflection peak? Is it a sample preparation problem? Is it part of the baseline? <image.png> Thanks Shay -- ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Please do NOT attach files to the whole list <alan.he...@neutronoptics.com> Send commands to <lists...@ill.fr> eg: HELP as the subject with no body text The Rietveld_L list archive is on https://urldefense.com/v3/__http://www.mail-archive.com/rietveld_l@ill.fr/__;!!Nmw4Hv0!w-yODRD0lzZ1lVAeDkHJr5sluosziIfM9HlNeLNAeVkQ2Ae6OCEp41_S7BkW0YXUmBPTUVFpKEddVhhq4fuaVV1NBQ$ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
