Hello Israel, thank you for ur answer, i did verify on the A.M. website, there's a pattern from synthetic Gehlenite, but the position of peak 2,8463 in the pdf...
i agree with you but the peak record i indicated is with distance d, for 2 theta it's 31,269 for my XRD spectra and 31,420 for PDF file record (77-1147), for...
Dear Abdo I believe that if there could be an error in lattice parameters and wavelength 2theta would have a maximum error of 0.1 or in an extreme case 0.2....
Dear all, i have a simple question. I work in structure determination of organometallics. When i refine the Biso global parameter, their value after refinement...
Dear Israel may ask about a possibility to suggest if my XRd data is shifted from standard PDF data, that mine has a different structure to the orginzl ...
