Calculation of Crystallite Size Distributions from X-Ray Line Broadening

The distribution of column lengths p(n)/N_c in a powder sample is given by the following combinations of the coefficients of the Fourier series expansion of the x‐ray diffraction line shape: $${\mathrm{p(n)/N}}_c{\text{=(2A}}_n-{\mathrm{A}}_{\text{n+1}}{\mathrm{-A}}_{\text{n−1}}{\mathrm{)/A}}_0{\mathrm{-A}}_1)$$ .
