Abstract
Photoelectron-spectroscopy studies of Ce${\mathrm{Al}}_{2}$, La${\mathrm{Al}}_{2}$, and the "chemically compressed" alloys ${\mathrm{Ce}}_{0.6}$${\mathrm{Y}}_{0.4}$${\mathrm{Al}}_{2}$ and ${\mathrm{Ce}}_{0.6}$${\mathrm{Sc}}_{0.4}$${\mathrm{Al}}_{2}$ were performed with use of synchrotron radiation. For all compounds the $4f$ binding energy is 2.55 \ifmmode\pm\else\textpm\fi{} 0.1 eV. These results, combined with previous bulk-property results, motivate a reevaluation of Anderson-model parameters and mechanisms as applied to Ce${\mathrm{Al}}_{2}$.
