Classical Point-Charge Model
In the simplest model of the crystal field, the point-charge model introduced by Bethe (1929), the lattice is replaced by an array of point charges placed at the nuclei of the constituent ions. A multipole expansion is made of the point-charge potential energy at the rare-earth site.
