Photoelectron Spectra of Pure Rh Metal and CuRh Alloys

Abstract

The photoelectron spectra of the valence bands have been measured on the pure Rh metal and Cu-based Rh alloys over the excitation energy range from 30 eV to 130 eV. The band occurring at 1.25 eV below the Fermi edge with the width of 0.5 eV is interpreted as being due to the virtual bound state. From the result of the virtual bound state the number of the electrons of the Rh virtual bound state and the phase shift for the d-partial component is estimated to be 8.79 electrons and 2.76 radians respectively. A satellite, which can be observed in valence band photoemission spectra for some transition metals, can not be detected for pure Rh metal.
