The electronic structures of FCC and BCC phases of sputter-deposited Fe-Cu and Fe-Ag alloy films have been studied using the tight-binding linear muffin-tin orbital method in conjunction with the coherent potential approximation. A simple treatment of the X-ray photoemission spectra based on the electronic density of states (DOS) and the atomic photoionization cross-sections of alloy constituents, is presented. The calculated XPS results are in good agreement with the recent experimental data on these alloys.
