Soft X-Ray Emission Spectroscopy Using Synchrotron Radiation

  title={Soft X-Ray Emission Spectroscopy Using Synchrotron Radiation},
  author={J. Nordgren},
This presentation describes soft x-ray emission spectroscopy and its recent developments based on the use of synchrotron radiation for the excitation. A brief account of instrumentation employed in such experiments is given, and a few areas of application in physics research are discussed. In particular, experiments in threshold and resonant soft x-ray emission spectroscopy are presented, and application to surface physics is briefly discussed. Also, the direction of future developments is…

Soft x-ray emission spectroscopy using monochromatized synchrotron radiation (invited)
Soft x‐ray emission spectroscopy is a common tool for the study of the electronic structure of molecules and solids. However, the interpretation of spectra is sometimes made difficult by overlaying
Resonant behavior in soft x-ray fluorescence excited by monochromatized synchrotron radiation.
Soft x-ray emission spectra of TiN, excited by monochromatized synchrotron radiation, have been recorded in a grazing-incidence spectrometer and a new type of resonance is observed in the Ti L emission spectrum, and interpreted as due to the decay of a quasiatomic intermediate state.
Synchrotron-radiation-excited soft-x-ray-fluorescence studies of Cu and Zn: On the validity of the sudden approximation.
Strong satellites are observed which can unambiguously be associated with the decay of multiply excited states, and this disproves recent claims of a breakdown of the sudden approximation in this regime.
Soft x-ray emission studies of adsorbates.
Soft x-ray emission spectroscopy is for the first time applied to surfaces and adsorbates and O K emission from adsorbed atomic oxygen on Ni and Cu and molecular CO on Ni(100).
