AbstractAbstract
[en] Auger first experiences in 1923 and thesis in 1926 on photoelectrons with a Wilson chamber are shortly presented. The two related techniques, Siegbahn XPS (X-ray Photoelectron Analysis) and Auger AES (Auger Electron Spectroscopy), are compared for surfaces analysis with advantages and disadvantages.

AbstractAbstract
[en] This paper presents Auger electron spectroscopy with a retarding field analyser designed for an advanced physics experiment carried out in 'Physics Laboratory II' at the Institute of Experimental Physics, University of Wroclaw, Poland. The authors discuss the process of setting up the experiment and the results of the measurement of Auger spectra. The advantages and disadvantages of the apparatus are discussed along with its implementation in the teaching process

AbstractAbstract
[en] Beginning with a chapter on symmetry and invariance, the theory of the Auger process is developed by considering the progressive breaking of symmetry as one goes from the simple hydrogenic model to a more realistic description of the many-electron atom. The calculation of Auger intensities and energies using different coupling schemes is also discussed from this angle, the results of important calculations are compared with experiment, and recent work on Auger satellites and correlation effects is reviewed. With a conscious departure from the emphasis on theory, the last chapter deals with surface Auger phenomena: after a brief survey of analytical methods, it described the features of Auger spectra in solids and gives a critical account of the principal aspects of surface Auger spectroscopy

AbstractAbstract
[en] Variation trends across the AnO2 series of An5f-electron covalent bonding and An5f→O3s, O2p→An5f charge transfer energies, are studied using DV-Xα relativistic spin-polarised computation of electronic structures applied to 11 'AnO8' clusters, from ThO8 to FmO8. It is found that the binding energies of 5f orbitals, therefore the An5f-O2p hybridisation, are increasing though the 5f orbitals are localising across the An series. In our calculations, the 3s and 3p ionic-like orbitals of O2- ions are included for the first time as LCAO-MO bases. Then, the conduction band is a mixing of O3s and An6d and its lower edge corresponds to an O3s-dominated state. Moreover, the calculated charge transfer (CT) energies of An5f→O3s and O2p→An5f transitions show the so-called tetrad effect when CT energies, respectively increasing and decreasing across the AnO2 series. It is pointed out that the tetrad effect here comes mainly from the special spin-polarised pattern of 5f levels and the increasing general trend of 5f binding energies. (orig.)

AbstractAbstract
[en] Auger electron spectroscopy (A.E.S.) allows to characterize the atoms lying at surfaces of amorphous and crystalline materials and to investigate their chemical bond. In the case of single crystals it is generally associated with LEED which gives information on the surface structure. After having recalled some principles about radiationless deexcitation of atoms and the related Auger transitions, the problems of interpretation of energy spectra in the case of a single atom and their of an atom bound to neighbours either of the same kind or of a different one, are discussed. Some applications of A.E.S. as an analytical method are finally described

La spectrometrie des electrons Auger permet de caracteriser les atomes situes a la surface d'un corps cristallin ou amorphe et de preciser la nature de leurs liaisons. Dans le cas de monocristaux elle est en general associee a la diffraction des electrons lents, ce qui permet d'avoir, en plus des renseignements sur la structure de la surface. Apres un rappel de la desexcitation non radiative des atomes et des transitions Auger correspondantes, les problemes que souleve l'interpretation des spectres d'energie sont traites d'abord dans le cas d'un atome isole puis dans celui d'un atome lie a des atomes voisins de meme espece ou d'especes differentes. On examine enfin quelques applications de l'analyse AugerOriginal Title

AbstractAbstract
[en] The composition of the surface of a solid body is generally different from that of the bulk. There are many problems that cannot be solved simply by an analysis of the elements, information on the binding states of the detected elements, or rather on the molecules, being required also. The results obtainable depend on the nature of the problem. Where general surface analysis is concerned, e.g. in the areas of corrosion, catalysis, and high polymer technology, ESCA permits substantial characterization of the binding states. SIMS is opening up new opportunities in the use of surfaces and surface analysis methods to identify and investigate the structures of small quantities of substances. In model experiments under idealized conditions (performed by UPS and ELS, for example) it is possible to arrive at fundamental conclusions regarding the adsorbate/substrate interaction. (orig.)

Ein Festkoerper ist an seiner Oberflaeche in der Regel anders zusammengesetzt als im Volumen. Bei zahlreichen Fragestellungen genuegt die Elementanalyse nicht; es werden Angaben zum Bindungszustand der nachgewiesenen Elemente, besser noch Aussagen ueber Molekuele gefordert. Die erzielbaren Ergebnisse haengen von der Problemstellung ab. In der allgemeinen Oberflaechenanalytik, z.B. in den Bereichen Korrosion, Katalyse, Hochpolymertechnologie gestattet ESCA eine weitreichende Charakterisierung der Bindungsverhaeltnisse. Beim Gebrauch der Oberflaeche und der Oberflaechenanalysenmethoden zur Identifizierung und Strukturaufklaerung geringer Substanzmengen weist SIMS neue Wege. In Modellversuchen unter idealisierten Voraussetzungen koennen grundlegende Aussagen zur Wechselwirkung Adsorbat/Substrat z.B. mit UPS und ELS gewonnen werden. (orig.)Original Title

AbstractAbstract
[en] We investigated the Autler–Townes splitting in photoelectron spectra of molecules steered by ultrashort laser pulses using the time-dependent wave-packet method. Structure of the Autler–Townes splitting was presented to analyze the information of a selective population of the dressed states. It was found that population transfer process, structure of photoelectron spectrum and pattern of Autler–Townes splitting can be controlled by adjusting the intensity, wavelength and delay time of laser pulses.
