AbstractAbstract
[en] The term 2F given to the ions Ce3+ and Yb3+ is due to an electron or to one hole, respectively, in the 4f configuration of the lanthanide elements. When the number of equivalent electrons (or holes) becomes larger than one, there is an increase in the number of terms. Considerations about the classification of terms to differentiate states of a given f sup(n) configuration are made on the basis of group theory. It is shown that different sets of quantum numbers are necessary to distinguish levels with the same representations and with different energies. (C.L.B.)
