UV Laser and VUV Photoemission from α and γ phase Cerium--Evidence for d state structure
Abstract
Photoemission data from polycrystalline α and γ phase Cerium films were obtained using HeI, HeII, NeI and NeII photons as well as a UV laser ( ~5 eV). The photon energy dependance was used to identify the origin of a number of features easily seen in the HeI valence band spectra but not discussed in the literature. One is attributed to an Auger process while others are attributed to structure in 5d conduction states. Changes in these features contribute significantly to the contrast between spectra from α and γ phase films. The novel, high quality data acquired with the laser will be compared to results from conventional photoemission experiments.
