چکیده
Argon 3-M23M23 Auger-electron spectra were measured in coincidence with Ka fluorescent x-rays in studies of Ar K-shell vacancy decays a t several photon energies above t h e K-threshold and on the 1 s 4p resonance in atomic argon. The complex spectra recorded by conventional electron spectroscopy are greatly simplified when recorded in coincidence with fluorescent x-rays, allowing a more detailed analysis of the vacancy cascade process. The resulting coincidence spectra are compared with Hartree-Fock calculations which include shake-up transitions in the resonant case. Small energy shifts of the coincident electron spectra are attributed to post-collision interaction with 1 s photoelectrons.

Auger electron angular distribution of double core-hole states in the molecular reference frame.
The Linac Coherent Light Source free electron laser is a source of high brightness x rays, 2×10(11) photons in a ∼5 fs pulse, that can be focused to produce double core vacancies through rapid sequential ionization. This enables double core vacancy Auger electron spectroscopy, an entirely new way to study femtosecond chemical dynamics with Auger electrons that probe the local valence structure ...
متن کاملAngle-resolved electron spectroscopy of laser-assisted Auger decay induced by a few-femtosecond x-ray pulse.
Two-color (x-ray+infrared) electron spectroscopy is used for investigating laser-assisted KLL Auger decay following 1s photoionization of atomic Ne with few-femtosecond x-ray pulses from the Linac Coherent Light Source. In an angle-resolved experiment, the overall width of the laser-modified Auger-electron spectrum and its structure change significantly as a function of the emission angle. The ...
متن کاملMulti-coincidence spectroscopy on interatomic Coulombic decay
The inner-shell ionized states in matter are subject to Auger decay. Auger spectra are considered as fingerprint images of the atom where the inner-shell hole is created. About a decade ago, Cederbaum and coworkers [1] proposed a new mechanism of electronic decay where the environment plays a role. For an isolated atom or molecule with an innervalence vacancy, Auger decay is often energetically...
متن کاملThe physical and chemical properties of ultrathin oxide films.
Thin oxide films (from one to tens of monolayers) of SiO2, MgO, NiO, Al2O3, FexOy, and TiO2 supported on refractory metal substrates have been prepared by depositing the oxide metal precursor in a background of oxygen (ca 1 x 10(-5) Torr). The thinness of these oxide samples facilitates investigation by an array of surface techniques, many of which are precluded when applied to the correspondin...
متن کاملRadiative auger effect and extended X-ray emission fine structure (EXEFS).
Radiative Auger spectra are weak X-ray emission spectra near the characteristic X-ray lines. Radiative Auger process is an intrinsic energy-loss process in an atom when a characteristic X-ray photon is emitted, due to an atomic many-body effect. The energy loss spectra correspond to the unoccupied conduction band structure of materials. Therefore the radiative Auger effect is an alternative too...
