The branching ratios in the circular dichroism of the rare-earth L{sub 23} edges are explained in a model where the 5d band is empty in the ground state. In the final state the 5d radial wave function contracts not only by the 5d-4f spin-spin interaction but by the complete exchange interaction. This explains the L{sub 3}/L{sub 2} ratios, the relative magnitude of the quadrupole contribution, and the dispersive shape of the signal in ionic compounds. {copyright} {ital 1997} {ital The American Physical Society}
