Abstract

PrOs4 Sb12 and other Pr compounds have been studied by means of bulk sensitive photoemission. The Pr 4f electronic state was probed by means of the Pr 3d→4f resonant photoemission (RPES). RPES spectrum was found to depend upon the photon energy (hν) especially above the Pr 3d^5/2 peak. It seems that the hν dependence is weak enough before the absorption intensity reaches the half of the peak.
