The deuteron-proton elastic scattering is studied in the multiple scattering expansion formalism. The contributions of the one-nucleon-exchange, single-and double scattering are taken into account. The Love and Franey parameterization of the nucleon-nucleon t-matrix is used, that gives an opportunity to include the off-energy-shell effects into calculations. Differential cross sections are considered at four energies, T d = 390, 500, 880, 1200 MeV. The obtained results are compared with the experimental data.

“…The explicit form of the amplitude M 2 D (k 1 , k 2 ) depends on the specific covariant model used to describe the deuteron and could be found elsewhere (see, e.g., [42,43,45]). Here, without loss of generality, we will use the Bethe-Salpeter (BS) formalism according to Refs.…”

The exclusive processes 2 H(e, e p)n, 3 He(e, e p) 2 H, and 3 He(e, e p)(pn) have been analyzed using realistic few-body wave functions and treating the final state interaction (FSI) within a generalized eikonal approximation (GEA), based on direct calculation of the Feynman diagrams describing the rescattering of the struck nucleon with the nucleons of the A − 1 system. The approach represents an improvement of the conventional Glauber approach (GA) because it allows one to take into account the effects of the nuclear excitation of the A − 1 system on the rescattering of the struck nucleon. Using realistic three-body wave functions corresponding to the AV18 interaction, the results of our parameter-free calculations are compared with available experimental data. It is found that in some kinematical conditions FSI effects represent small corrections, whereas in other kinematics conditions they are very large and absolutely necessary to provide a satisfactory agreement between theoretical calculations and experimental data. It is shown that in the kinematics of the experimental data that have been considered, covering the region of missing momentum and energy with p m 0.6 GeV/c and E m 100 MeV in the perpendicular kinematics, the GA and GEA predictions differ only by less than 3-4%.

Exclusive charge exchange reaction pD↦n(pp) within the Bethe-Salpeter formalism

The exclusive charge exchange reaction pD → n(pp) at intermediate and high energies is studied within the Bethe-Salpeter formalism. The final state interaction in the detected pp pair at nearly zero excitation energy is described by the 1 S 0 component of the Bethe-Salpeter amplitude. Results of numerical calculations of polarization observables and differential cross-section persuade that, as in the non-relativistic case, this reaction (i) can be utilized as a "relativistic deuteron polarimeter" and (ii) delivers further information about the elementary nucleon-nucleon charge-exchange amplitude.
