Binding energies and heat-of-formation data for USbxTe1-x and UAsxSe1-x compounds as derived from photoelectron spectroscopy

Using high-resolution photoelectron spectroscopy with synchrotron radiation we have accurately determined the core-level binding energies in the nonuranium atoms in USbxTe1-x and UAsxSe1-x as a function of the stoichiometric composition. With the use of a Born-Haber cycle a relation between the measured shifts and heat-of-formation data for these compounds is formulated. The analysis demonstrates that photoelectron spectroscopy can become a most valuable method for deriving new heat-of-formation data. © 1982 The American Physical Society.
