Deeply Virtual Compton Scattering experiment at  Jefferson Lab Hall B , with CLAS12, large acceptance spectrometer. Goals: Theoretical concepts as Generalized Parton Distributions (GPD), enable to probe with a dramatic accuracy the nucleon structure, and access the quark confinement in hadrons.
Scientific challenges and project framework   The COCOTIER project (for short-range COrrelations and Isotopic spin at R3B - COrrélations à COurte porTée et spin IsotopiquE à R3B) aims at studying the short-range correlations in the exotic nuclei produced by fragmentation by the radioactive ion beam factory FAIR at GSI.
This experiment aims to provide accurate data on actinide neutron-induced fission fragment characteristics (mass distributions, kinetic energy) and neutron multiplicities in the energy range between 500 keV and 20 MeV. Those data are of particular interest for the nuclear community in view of the development of the fast reactor technology.
Objectives While the heaviest element on earth is 238-uranium (with traces of Pu and Np in natural nuclear reactors) whose lifetime is 5 billion years, the last 60 years have seen the synthesis of dozens of new elements in laboratory, with shorter lifetimes.
Hadron electromagnetic form factors parametrize the internal structure of hadrons, the dynamical distribution of magnetization and charge created by the inner constituents.  They are considered fundamental quantities as they are a privileged background for interplay between theory and experiment.
La nature de ces nouvelles fonctions     Des progrès théoriques importants survenus dans les cinq dernières années permettent d'étendre considérablement la notion de distributions de partons dans un nucléon ou un méson.
The future superconducting linear accelerator of Spiral2 will provide very high intensity of stable ions beams. They can be used to produce nuclei with very low cross sections, like superheavy elements or neutron deficient nuclei close to the limit of stability.
The high-intensity stable beams of the superconducting linear accelerator of the SPIRAL2 facility at GANIL coupled with the Super Separator Spectrometer (S3) and a high-performance focal-plane spectrometer will open new horizons for the research in the domains of rare nuclei and low cross-section phenomena at the limit of nuclear stability.
