Abstract
The x-ray photoemission spectra of the valence bands of Hf metal and of several HfC x N y O z compounds have been measured and are compared to existing band structure calculations. The density of states at the Fermi energy of the HfC x N y O z compounds correlates strongly to their superconducting transition temperatureT c . A calculation of theT c values within the frame work of strong coupling superconductors indicates that the phonon spectrum and the electron phonon interaction is approximately constant within the series HfC x N y O z .
