Vacancies in the L1 shell of atoms and molecules can decay non-radiatively via Coster-Kronig decay whereby the vacancy is filled by an electron from the L2,3 shell while a second electron is emitted into the ionization continuum. This process is akin to Auger decay, but in contrast to Auger electrons, Coster-Kronig electrons have rather low kinetic...
An existing semi -empirical model to calculate the compound sputter yields is used to fit a large set of literature data on oxide sputter yields which consists of data for 21 different materials, and 65 datasets. The dedicated fitting procedure enables to link the surface binding energy of the metal and oxygen atoms with the oxide cohesive energy. ...
Since more than 100 years, the adsorption of the radioactive noble gas radon (222Rn) is performed on activated charcoal at cryogenic temperatures. There is little-if any-progress in the field of radon adsorption at ambient conditions to facilitate the development of simple and compact radon adsorption systems. We report here on the truly remarkable...
The Lennard-Jones (LJ) potential function is widely employed in molecular dynamics simulations. In this study, the LJ potentials under different characteristic diameter sigma and characteristic energy epsilon were simulated, and the changes in properties such as number density, total energy, phase transition latent heat, and phase transition temper...

The closed-shell nature of Xe atoms precludes the formation of Xe-Xe bonds other than based on van der Waals interactions. Here, we present experimental evidence showing that the complexation of Xe atoms to a Au+ ion leads to stabilization of a Xe-Xe interaction going beyond purely dispersive. Infrared spectroscopy is used to identify the geometry ...

The physicochemical properties of small metal clusters strongly depend on their precise geometry. Determining such geometries, however, is challenging, particularly for clusters formed by multiple elements. In this work, we combine infrared multiple photon dissociation spectroscopy and density functional theory calculations to investigate the lowes...
