The neutrons for science (NFS) facility is a component of SPIRAL-2, the new superconducting linear accelerator built at GANIL in Caen (France). The proton and deuteron beams delivered by the accelerator will allow producing intense neutron fields in the 100 keV-40 MeV energy range. Continuous and quasi-mono-kinetic energy spectra, respectively, will be available at NFS, produced by the interact...
The advantages to study charge–symmetry breaking and especially the phenomenon of f0 −a0 mixing in nucleon–nucleon and deuteron–deuteron induced reactions are discussed.
Differential and total breakup cross sections as well as vector and tensor analyzing powers for p-d scattering are studied for energies above the deuteron breakup threshold up to E lab = 28 MeV. The p-d scattering wave function is expanded in terms of the correlated hyperspherical harmonic basis and the elastic S-matrix is obtained using the Kohn variational principle in its complex form. The e...
The Coulomb interaction between the two protons is included in the calculation of proton-deuteron breakup and of three-body electromagnetic disintegration of 3 He. The hadron dynamics is based on the purely nucleonic charge-dependent (CD) Bonn potential and its realistic extension CD Bonn + ∆ to a coupled-channel two-baryon potential, allowing for single virtual ∆-isobar excitation. Calculation...

Realistic solutions of the spinor-spinor Bethe-Salpeter equation for the deuteron with realistic interaction kernel including the exchange of π, σ, ω, ρ, η and δ mesons, are used to systematically investigate relativistic effects in inclusive quasi-elastic electron-deuteron scattering within the relativistic impulse approximation. Relativistic y-scaling is considered by generalising the non rel...
We propose a precision measurement at low momentum transfer ( GeV ) of the Gerasimov-Drell-Hearn integral for the deuteron using the Hall B CLAS detector. By combining these data with the proton data taken under similar conditions (approved E03-006) we can extract the GDH integral on the neutron. These data will provide a benchmark for neutron Chiral Perturbation Theory ( PT) calculations. Also...
The reaction νd → µ − ∆ ++ n is studied in the region of low q 2 to investigate the effect of deuteron structure and width of the ∆ resonance on the differential cross section. The results are used to extract the axial vector N − ∆ coupling C A 5 from the experimental data on this reaction. The possibility to determine this coupling from electroweak interaction experiments with high intensity e...
The role of final state interaction in η photoproduction on a deuteron as well as on three-body nuclei is investigated within few-body scattering theory. Deviation of the theory from the available experimental results is briefly discussed. 1. Incoherent η photoproduction on a deuteron Photoproduction of η mesons on the deuteron near threshold is strongly influenced by final state interaction (F...
