4f-ionization of atomic cerium

The binding of the 4f electron in a cerium atom is investigated for general shapes of the 4f wave function. There is no activation barrier for 4f-ionization, in contradiction to an earlier calculation by Schlüter and Varma, who assumed a hydrogenic form. The existence of a second stationary electron...

Summary:The binding of the 4f electron in a cerium atom is investigated for general shapes of the 4f wave function. There is no activation barrier for 4f-ionization, in contradiction to an earlier calculation by Schlüter and Varma, who assumed a hydrogenic form. The existence of a second stationary electronic structure with extended 4f electrons and the “bistability model” developed from it to explain spectroscopic data in Ce compounds can be ruled out on energetic grounds.
