A simple tensorial contraction method has been developed to obtain analytical formulae for X‐ray resonant magnetic scattering. First, the method has been applied considering electric dipole–dipole and electric quadrupole–quadrupole scattering in the isolated‐atom approximation. The results have been compared with previous work. The same method has then been extended to non‐spherical systems by deriving new phenomenological formulae.
