摘要：

Thomson scattering by rare-earth multipoles is a valuable technique for determining orbital structures in rare-earth systems. In the present paper, the formalism describing the relation between the magnetic and multipolar structures in cubic systems is extended to the fourth- and sixth-order multipoles. The associated x-ray scattering amplitudes are written using the cubic irreducible representations and calling in play appropriate Stevens equivalent operators. This paper is intended to provide a rigorous framework for the interpretation of multipolar scattering experiments on magnetically or orbitally ordered systems.
