AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
We present a new experiment to monitor ionized atom and mass selected cluster depositions in real time using specular reflected thermal helium scattering. Monomer Ag ions with an incident kinetic energy of E/sub dep/=20 eV and E/sub dep/=95 eV create surfa ...
We have determined equilibrium geometries and electronic properties of neutral and anionic Cu-n (n = 2,9) clusters by means of first principles calculations in which s and d electrons are treated on equal footing. We find that the calculated electronic den ...
High-resolution core and valence band photoemission as well as photoinduced Auger spectra of metallic Sn, polycrystalline SnO and SnO2 ((110) natural single-crystal cassiterite and polycrystalline) samples were measured in order to give information on loca ...
Environmental effects on electronic states of small mols. in solid rare gases and in liqs. have severe consequences on the photochem.; examples for valence, Rydberg and ionic states as well as the connection to photochem. dry etching are treated. The repul ...
We introduce an approach to investigate thermal effects on the photoelectron spectra of small clusters. By combining first-principles molecular dynamics and a simplified scheme to account for final-state relaxation effects, we obtain averaged excitation sp ...
Radiative transfer is often the dominant energy transport channel in inertial confinement fusion experiments. It is a basic process needed in order to understand the behaviour of astrophysical plasmas, like stellar atmospheres and the inner parts of stars. ...
We present a new experiment which is able to monitor mass-selected cluster depositions in red time using specular reflected thermal helium scattering. Ag/sub 7//sup +/ with an incident energy of 2.86 and of 13.6 eV/atom is deposited on Pd(100) at different ...
Local density functional theory within the framework of the Car-Parrinello method has been used to study the structural parameters and the energetics of offretite, when a Si4+ ion is substituted by (Al3+, H+). The calculations have been performed on a peri ...
Abstract Using Fefferman's analysis of the quantum electron-proton gas, we give a rigorous proof of ionization equilibrium in this system. Ionization equilibrium phases are obtained as low-density and low-temperature limits, letting the chemical potentialm ...
A systematic study of the mass spectra of particles formed in a supersonic nozzle expansion of Zn, Cd, and Hg vapors together with Na was performed. The particles discussed in this paper contain only 1 heavy atom and
