The Fourier method was developed to calculate other important variables in the crystalline structure, such a strain, which is equal to 7.4828 x 10 −3 instead of the mean square strain and the energy density of the strain, which is equal to 2799614.7 dyne / cm 2 and the stress equal to 7.4828 x 10 8 dyne/cm 2 . The results obtained from the Fourier method for calculating other parameters of the manganese oxide lattice for each peak of x-ray diffraction peaks such as the texture coefficient, its mean value equal to 0. and the micro strains, which its mean value equal to 4.47 × 10 −3 dislocation density, its mean value are equal to 37.3 (lines .m −2 ) and the specific surface area its mean value is equal to 19,58432 of crystalline volume. A comparison was also made between the values of the square of strain and the apparent strain.
