We have performed relativistic molecular orbital calculations for the valence band structure of uranium monocarbide (UC), using the discrete-variational Dirac-Slater (DV-DS) method. We examine three kinds of model clusters (UC6, CU6, CU6C18) for the bulk electronic structure of UC. The calculated valence band spectrum (CU6C18) agrees with the experimental X-ray spectrum at peak position and intensities as well. The peaks in the experimental spectrum are assigned to the corresponding U and C orbital components.
