General information
Organisation
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

MODELLING LIGHT ANTI-ION REACTIONS ON ATOMIC NUCLEI

Job description
The anti-(p, n, d, t, 3He, 4He)-nucleus reactions are both instructive and complicated to study. In addition to knowledge of the products of the antinuclon-nucleon reaction, they require the- nuclear environment to be taken into account, in particular the interactions in the final state.
Antiproton-nucleon reactions are/will be used/studied in particular at Cern's antiproton decelerator (AD) ring and at the FAIR facility in Germany to understand the behaviour oft antimatter. Reactions with light anti-ions (dbar, 3He-bar, for example) are of more recent interest, in particular with the GAPS (General AntiParticle Spectrometer) experiment, which aims to measure the fluxes of these particles in cosmic rays. The idea is to identify dark maJer, of which these particles are decay products, and whose measured quantities could 'easily' emerge from the cosmic background noise.
Recently, antiproton-nucleus reactions have been added to the INCL (IntraNuclear Cascade Liège) nuclear reaction code developed at the CEA (Irfu/DPhN) and this code is currently being implemented in the Geant4 transport code. The aim of the proposed thesis is to now include the reactions anti-(d, t, 3He, 4He)-nucleus in the INCL code.
