In this paper they present inverse photoemission spectra recorded from the Cu(111) and Cu(001) surface. To record these data they have used a new electron source and a novel form of photon detector based on the chromatic aberration properties of a LiF lens. This arrangement, described in more detail elsewhere, gives us both improved energy and momentum resolution over their previous experiments. The spectra show both the image potential derived states and the normal crystal potential derived surface states. It is found that the image potential states have different binding energies on the two planes, namely 0.6 eV on the Cu(001) surface and 0.9 eV on the Cu(111) surface.
