STUDIES OF EFFECT OF ATOM POSITIONS ON THE NEUTRON DIFFRACTION INTENSITIES (Pages : 38 - 43)

The occurrence of a diffraction line or particular reflection is determined by diffraction conditions. The present work is a theoretical study in which the condition of reflection for polycrystalline Si with atoms at the various crystal lattice sites in the Fd3m space group have been found out by calculation the structure factors for different reflections. Diffraction patterns have been simulated for the distribution of atoms at different ratio over the sites and the intensities of the Bragg peaks are compared. The effect of atom positions on intensities has thus been found out. This result will be of help to the scientist working in material science at different laboratory in home and abroad.Download
