Abstract

The densities of the unoccupied states of Cu 90 Y 10 and Cu 74 Y 26 alloys have been probed by inverse photoemission in the ultraviolet range and compared with those of pure Cu and Y. This, along with direct photoemission spectra, allows for the determination of Cu 3 d - and Y 4 d -band energy positions and widths in the joint density of empty and occupied states. From these data an increase of empty d -like states along with a resulting decrease of empty sp -like states is revealed as well as a hybridization of the Cu 3 d and Y 4 d levels.
