I agree with a Ni absorption edge, possibly with a Kβ peak around 38° 2θ.

Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> Hello Shay, I think it is probably related to "tube tails". You can read about this in the literature (e.g., on the BGMN web site) and you can model it in some Rietveld software such as Topas. You don't normally notice this but it becomes apparent with higher-intensity peaks.

Please exercise caution when clicking links or opening attachments from external sources. Hey Shay, Are you using a motorized slit during the measurement? These may open up abruptly to compensate for the angular dependence of the footprint and thus generate an abrupt increase in the intensity. Hope it helps :) On Sun, Sep 3, 2023, 8:50 AM Shay Tirosh <[email protected]<mailto:[email protected]>> wrote: Dear Rietvelders I am attaching a zoom-in on a diffraction profile. 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?
