Abstract
The branching ratios in the circular dichroism of the rare-earth edges are explained in a model where the band is empty in the ground state. In the final state the radial wave function contracts not only by the - spin-spin interaction but by the complete exchange interaction. This explains the ratios, the relative magnitude of the quadrupole contribution, and the dispersive shape of the signal in ionic compounds.
