Based on the well established group—theoretical methods we have calculated the Clebsch—Gordan coefficients (CGCs) for some crystals of the space group C46v. The linear combinations of the CGCs determine the elements of the first order scattering tensors while the second order scattering tensors are bilinear combination of the CGCs. Some other applications of the calculated CGCs are also discussed.
