Electron spectroscopy using ultra brilliant synchrotron X-ray sources

Abstract

Electron spectroscopy using ultra brilliant synchrotron X-ray sources. Journal of Electron Spectroscopy and Related AbstractThe development of photoelectron spectroscopy since the early days of the technique is discussed. The focus is on the interaction between instrumental development and scientific achievements. In particular the opportunities provided by the increasingly brilliant synchrotron radiation sources are discussed. The contribution is focused on core level studies. The recent development is demonstrated by using selected examples obtained at today´s most advanced synchrotron radiation facilities. The spectral resolution and intensity that can be reached at these facilities reveal new effects and provide detailed information on the investigated systems. The examples are mainly taken from studies of atoms and molecules where different effects can be most accurately identified and separated.2

Attosecond Transient Absorption Spectroscopy of doubly-excited states in helium

“…Photoelectron spectroscopies have been particularly useful to investigate correlated electronic states and their dynamics in atoms and molecules. Third-generation synchrotron, for example, generate highly monochromatic extreme ultraviolet (XUV) and x-ray radiation that enables the measurement of ionization spectra in stationary regime and with high energy resolution [3][4][5][6][7][8][9][10]. These measurements, however, provide only limited information on how the photoemission process unfolds in time.…”

Recoil lineshapes in hard X-ray photoelectron spectra of large molecules – free and anchored-on-surface 10-aminodecane-1-thiol

“…Each of these categories gives a contribution to the total recoil lineshape, but these individual contributions F r,n (E r ) now have distinct characteristics depending on the type of motion described by the oscillator n. The overall recoil lineshape (as convolution) is characterized by the recoil-induced energy shift, broadening and asymmetry. Note that as the origin of the model still lies in eqn (3) and involves the translational and rotational thermal motion by the respective oscillators, the lineshape includes the translational [32][33][34] and rotational 26,27 Doppler broadening.…”

Uppsala and Berkeley: Two essential laboratories in the development of modern photoelectron spectroscopy

“…31 The experimental and theoretical study of core-level line profiles is very demanding and can only be performed using the most modern electron spectroscopy based on synchrotron radiation beamlines and modern theoretical techniques. 32 In 1974, an HP5950A instrument was delivered to Uppsala and there were then two world-class electron spectrometers (one for solids and surfaces, and one for gas samples) in the laboratory. Two of the authors of this report (N.M. and S.S.) responsible for these instruments were Ph.D. students.…”
