Abstract

The photoemission spectrum (PES) of PrFe₄ P₁₂ is calculated by using the non-crossing approximation for the impurity Anderson model, in which the intensity of the pf-mixing is estimated by the LMTO band calculation for LaFe₄ P₁₂. The large intensity of PES just below the Fermi level can be explained in terms of many f² multiplets that accompany a hole in the valence band. The temperature dependence of PES is consistent with dominant f³ intermediate states rather than f¹ ones.
