I´m new in this interesting in Data Interpretation in qualitative analysis and hope you can help me with this:
I have a powder Ag sample (containing little quantity of Ag2O) and have performed a WDXRF qualitative analysis (Rhodium target) with the LiF220 analysing crystal. I can clearly identify the AgKalpha, AgKbeta (fisrt and second order), Rh Kalpha and RhKbeta peaks. My question is about the presence of two broad peaks around these º2theta positions: 30.56º and 34.76º. Might these be half order AgKalpha, Kbeta lines (forbidden reflections) due to inhomogeneities of the crystal? Is the first time I see them.
