The contribution of incoherent single pion photoproduction to the spin response of the deuteron, i.e., the asymmetry of the total photoabsorption cross section with respect to parallel and antiparallel spins of photon and deuteron, is calculated over the region of the ∆-resonance with inclusion of final state NNand πN-rescattering. Sizeable effects, mainly from NN-rescattering, are found leadin...

The effect of non-locality in the NN interaction models is examined. It is shown that this feature can explain differences in predictions made from models evidencing a difference with this respect. This is done for both static and dynamical observables, taking into account that a non-local term can be transformed away by performing a unitary transformation. Some results for the deuteron form fa...

In plane wave one-body approximation the reaction of deuteron photodisintegration is considered in the framework of the Bethe–Salpeter formalism for two-nucleon system. Results are obtained for deuteron vertex function, which is the solution of the homogeneous Bethe–Salpeter equation with a multi-rank separable interaction kernel, with a given analytical form. A comparison is presented with pre...

CLAS photoproduction data on deuterium and hydrogen targets have been analyzed in a search for an exotic baryon state with strangeness S = +1, the Θ (originally named the Z). This resonance was predicted recently in theoretical work based on the chiral soliton model as a lowest mass member of an anti-decuplet of 5-quark states. The reaction γd → pKKn, which requires a final state interaction in...

The mechanism of pHe backward elastic scattering is studied. It is found that the triangle diagrams with the subprocesses pd →3Heπ0, pd →3Heπ0 and p(pp) →3Heπ+, where d and pp denote the singlet deuteron and diproton pair in the S0 state, respectively, dominate in the cross section at 0.3-0.8 GeV, and their contribution is comparable with that for a sequential transfer of a np pair at 1-1.5 GeV...

We calculate the second-order corrections to the atomic energy level shifts in ordinary and muonic deuterium due to virtual excitations of the deuteron which are important for ongoing and planned precise experiments in these systems. For light atoms a method can be used in which the shift is expressed as integrals over the longitudinal and transverse inelastic structure functions of the nucleus...

Nuclear deep inelastic scattering is considered in the framework of a model in which the current operator explicitly satis es Poincare invariance and current conservation. The results considerably di er from the standard ones at small values of the Bjorken variable x. In particular, it is impossible to extract the neutron structure functions from the deuteron data at x < 0:01 and we predict tha...
