Вероятности оже-переходов и сечения эмиссии электронов при распаде вакансии на 2pπ-орбитали в квазимолекуле Ne-=SUP=-+-=/SUP=--Ne

The Auger transition probabilities are calculated while filling a vacancy on 2pπ orbital in a Ne+-Ne quasimolecule, a short-lived system which is formed when ion and atom approach each other and decays when they scatter. For the first time calculations were performed for various degrees of particles ionization in quasimolecule. It was found that with increase of collision energy and decrease of distance of the closest approach of particles the system ionization degree increases very significantly (from 2 to 6). Using of the quantum mechanical approach and taking into account the dynamics of collisions made it possible for the first time to describe quantitatively the experimental spectra of Auge electrons for a complex many-electron quasimolecule. From the whole variety of possible Auger decay channels the dominant contribution of the transition was established, from the initial 3dπ-3dπ state to the 2pπ orbital.

Etching of ZnO films by a focused flow electrons with medium energies (up to 70 keV)

Consideration is given to the results of the study of etching processes ( 200 nm/min) of a ZnO film by a focused electron beam with medium energy (70 keV) under vacuum conditions of 910-5 Pa. It was shown that the construction of a model of the ZnO film etching during electron bombardment, taking into account the likely thermal desorption and electron-stimulated desorption, is not confirmed by calculations. A possible etching mechanism based on the radiolysis caused by Auger decay in near-surface layers of ZnO films is proposed.

Multiple valence electron detachment following Auger decay of inner-shell vacancies in gas-phase DNA

A K-shell vacancy in DNA that is induced by a (therapeutically relevant) soft X-ray of MeV carbon ion, decays by Auger processes accompanied by emission of at least 3 low energy electrons.
