A mathematical procedure used for correcting the interference between two nearest first order overlapping lines is described. The intensity of the ‘composite’ peak is assumed to be a linear superposition of the individual components; the shift in angular position of the sample. The proposed method is based on the dependence existing between the different parameters involved, which can be represented by a mathematical relationship of the [R i ]=[k ij ] [C j ], where R i is the observed intensity, measured at the theoretical 2θ values for the elements involved, K ji are characteristic constants of the angular position and C j the concentration of the elements.
