Linear magnetic and alignment dichroism in Auger–photoelectron coincidence spectroscopy
Auger–photoelectron coincidence measurements for polarized targets are theoretically considered. We present a general expression for the cross section of sequential double photoionization of polarized atoms within the two-step model. Linear magnetic and alignment dichroism in coincidence experiments is discussed in more detail. For illustration, we made ab initio calculations based on the multi...
متن کاملPhotoelectron-Auger electron coincidence spectroscopy of free molecules: new experiments
Photoelectron-Auger electron coincidence spectroscopy probes the dicationic states produced by Auger decay following the photoionization of core or inner valence levels in atoms, molecules or clusters. Moreover, the technique provides valuable insight into the dynamics of core hole decay. This paper serves the dual purpose of demonstrating the additional information obtained by this technique c...
متن کاملThe LVV Auger line shape of sulfur on copper studied by Auger photoelectron coincidence spectroscopy.
We have studied the line shapes of Cu(0 0 1)-p (2 × 2)S L2VV and L3VV Auger decay by means of Auger photoelectron coincidence spectroscopy. Measuring the LVV Auger spectrum in coincidence with S 2p1/2 and 2p3/2 photoelectrons respectively, we have been able to separate the two overlapping Auger spectra and determine their intrinsic line shapes. The two Auger transitions, though shifted in energ...
متن کاملThe Potentiodynamic Behavior of Copper in NaCI Solutions Studied by Auger and Photoelectron Spectroscopy
The potentiodynamic behaviour of copper in brine solutions was studies. Auger and photo-electron spectroscopy were used together with electrochemical methods. It is demostrated that the passivation observed in potentiodynamic curves is due to a surface film formation on a copper electrode. It is concluded that this film must be copper (I) chloride in nature. Effect of different factors on poten...
متن کاملAuger photoelectron coincidence spectroscopy studies: Trends in the L2,3-M4,5M4,5 line shapes across the 3d transition-metal series
The Auger-emission process from solids can be very complex, with a variety of processes producing intensity in the final spectra. The L2,3-M 4,5M 4,5 (L2,3-MM ) Auger spectra of the 3d transition metals, in particular, show many complicating effects. Auger photoelectron coincidence spectroscopy ~APECS! is a technique that can be used to elucidate the source of this complexity. In the APECS expe...
