Resonant photoemission in titanium metal

Abstract

The photoionization cross section of the titanium 3d band, including the contributions from direct photoemission and autoionization, has been measured using synchrotron radiation on a wide photon energy range (21 – 110 eV). Particularly, we have concentrated on the resonant behavior of the valence band near the 3p and 3s threshold in which the influence of autoionization appears as drastic fluctuations of a resonant profile. In addition, we have examined subthreshold Auger emission that should already occur below the threshold energy.
