3p multiplet structure of Ti studied by photoelectron spectroscopy — •Kai Godehusen1, Sandra Brünken1, Birgit Kanngießer1, Peter Zimmermann1, and Michael Martins2 — 1Institut für Atomare und Analytische Physik, Technische Universität Berlin, Hardenbergstr. 36, D-10623 Berlin, Germany — 2Institut für Experimentalphysik, Freie Universität Berlin, Arnimallee 14, D-14195 Berlin, Germany
The 3p photoemission of free Ti atoms has been studied using synchrotron radiation of the storage ring BESSY II in Berlin.
The 3p−1 electron spectrum of Ti is dominated by a strong 3p−3d interaction. It also shows extensively broadened low-spin states. This term dependent lifetime and the strong 3p−3d interaction can also be seen in the 3p spectra of other 3d transition metals. We have done Hartree-Fock calulations which support our findings.
