Abstract

We have measured the4d–4fhigh-resolution resonant photoemission spectra ofRFe4P12(R = La, Ce, Pr),PrSn3andPrAl2. The Ce and Pr4fspectra show the spectral features corresponding to a strongly hybridized system. However, the$f_{5/2}^1$and the3H4peaks located just below the Fermi energy in the Ce4fand Pr4fspectra, respectively, are observed as a shoulder instead of the prominent peak expected for the strongly hybridized or high-Kondo temperature systems.
