How to index peaks in x-ray diffraction
WebPeak width is a measure of the broadness of the peak. For example at low angles a small value (e.g. 0.05°) would indicate a sharp peak whereas a large value (e.g. 0.2°) would indicate a broad peak. Several parameters … Web7 jan. 2024 · In neutron diffraction you will see high intensity (nuclear) peaks at high angle. Nontheless, with neutron you also have scattering by unpaired electrons forming a …
