    Abstract

    The U 4f x-ray photoemission spectroscopy spectra have been measured on (Formula presented), UC, (Formula presented), and (Formula presented)(Formula presented). The measured spectra are decomposed into the main lines and the satellites by nonlinear least-squares fitting to the theoretical line shapes proposed by Kotani and Toyozawa. The occurrence of one symmetrically shaped satellite associated with the asymmetric main band predicts very weak configuration mixing in the ground state. The relations of the satellite intensity and the singularity index to the width of the satellite line are discussed in conjunction with the magnetic properties of the materials.
