Auger resonance decay process in Ar 2p shell excitation and ionization

Multielectron Spectroscopy : Auger decays of the Argon 2p hole

All the different Auger decay paths of Argon 2p holes have been characterized using a time of flight spectrometer of the magnetic bottle type. All electrons (the photoelectron and up to three Auger electrons) are detected in coincidence and resolved in energy. Double Auger decay is shown to proceed either through a direct process or by intense cascade paths, implying highly excited autoionizing...

KLL Auger decay in free aluminum atoms

The KLL Auger transitions in free atoms present the simplest nonradiative electronic decay channel and therefore are of fundamental theoretical interest. Atomic spectra are advantageous for detailed theoretical analysis because the solid-state and molecular environments cause additional demands for the interpretation of spectra. Besides Ne 1,2 and Ar 3 rare gases, only the KLL spectra of Na 4 a...

مطالعه دینامیک آبشاری اتم کائونیک نیتروژن به روش مونت کارلو

 Cascade dynamics of kaonic nitrogen atom (K-N) in a gaseous target was simulated using a simple model. In this model the radiative transitions, internal Auger, K-electron refilling, nuclear absorption, and kaon decay processes were included. The effect of the K-electron refilling process on some of quantities of cascade dynamics such as X-ray yields, the averaged K-electron shell number, fract...

Energy and angular distributions of electrons emitted by direct double auger decay.

We have observed the direct L(2,3)MMM double Auger transition after photoionization of the 2p shell of argon by angle-resolved electron-electron coincidence spectroscopy. The process is responsible for about 20% of the observed Auger electron intensity. In contrast to the normal Auger lines, the spectra in double Auger decay show a continuous intensity distribution. The energy and angular distr...
