Equipe AMA

AMA : Atomes, Molécules et Agrégats.

Group Leader : Jean-Yves Chesnel

The AMA members are exploring the interaction of ions with dilute matter ranging from isolated molecules to atomic or molecular clusters. Most of the attention is focused on the stability and the fragmentation dynamics of multi-atomic systems after their excitation/ionization by ion impact at velocities of a few tenths of atomic velocities.

Following its long tradition, the AMA team investigates collision-induced mechanisms of fundamental interest, such as electron interference effects and shakeoff processes. In addition, a major goal of the team is to provide valuable upstream information relevant for societal issues. To gain new insights into radiation damage processes, the team aims to describe, at the molecular level, the early stages of ion-induced fragmentation of biomolecules. Also, AMA investigates reactions involving polycyclic aromatic hydrocarbons, carbon clusters and fullerene precursors which are of prime interest for astrophysics and atmospheric chemistry.

The highlights obtained by the AMA team, as well as its attractiveness through its collaborations and contributions to networks and conference organization, have recently been supported through the recognition of the exceptional achievements of one of its young members : Alicja Domaracka-Rousseau received the “médaille de Bronze” in 2015 from the CNRS.
