Dependence of the Stark structure on the energies of the multiplets
Kornienko A. A., Dunina E. B.
A detailed study of configurational-mixing effects in / systems reveals that the crystal-field Hamiltonian contains some new terms, which depend on the energies of the multiplets. When these terms are taken into account, it becomes possible to resolve some experimental data, on the Stark splitting of low-and high-lying multiplets, which have looked contradictory from the standpoint of the ordinary theory. These new terms can be thought of as corrections to the parameters of the even crystal field which depend on the energies of the multiplets. Analytic expressions are derived for these terms. These expressions make it possible, for the first time, to work from an analysis of the energy spectrum to determine the parameters of the odd crystal field, which is responsible for intensity characteristics of the optical spectra of / systems.
