PIIM - UMR 7345
Physics of the Interactions of Ions and Molecules
PIIM is a joint research laboratory of the CNRS and Aix-Marseille University located in Marseille, France. It brings together physicists and physical chemists who study dilute media - such as gases, plasmas and beams of ions, atoms and/or molecules - as well as their interactions with matter. Our researchers aim to understand the physical phenomena in these media in order to analyse and characterise matter.
