Aujourd'hui, les anneaux synchrotrons, tels que l'ESRF à Grenoble ou le synchrotron SOLEIL sur le plateau de Saclay, sont des sources intenses de photons (de l'infra-rouge aux rayons X). De nombreuses équipes de l'IRAMIS réalisent régulièrement des expériences autour de ces sources.

In photoemission, the initial-state k⊥ can be deduced if the final-state surface-perpendicular dispersion E(k⊥) into the crystal bulk is known. The widely used free-electron-like (FE-like) model fails for many quasi 2D systems.

Melt and fluid inclusions in olivines from the last 197 days long eruption of Piton de la Fournaise (Réunion Island) that began March 9, 1998, have recorded a range of volatile partial pressures.

K-edge X-ray absorption and 2p-XPS spectra of 3d-element oxides present spectral features which cannot be explained within a simple one-electron model.

Micro-experimental studies require the use of diamond anvil cells, allowing observation and in situ characterization of the studied phase equilibrium using classical spectroscopy techniques (Infrared, Raman, X-Ray Fluorescence, X-Ray diffraction…).

Photoelectron emission microscopy combined with intense photon sources is becoming a powerful analytical tool with both spatial resolution down to a few nanometers and spectroscopic capabilities.
Prediction of long term corrosion (on several hundred years) of low alloy steels is a crucial issue in several research domains: metallic cultural heritage conservation, civil engeeniring, etc.

General objectives  We aim at understanding the microscopic mechanisms controlling the formation of nanoparticles. Different types of NPs are studied in the LIONS and among them gold NPs have already been the subject of several achieved PhD (B. Abécassis and F.
