The relativistic impulse approximation for the exclusive electrodisintegration of the deuteron

et al. 2007

View full text Add to dashboard Cite

The electrodisintegration of the deuteron in the frame of the Bethe-Salpeter approach with a separable kernel of the nucleon-nucleon interaction is considered. This conception keeps the covariance of a description of the process. A comparison of relativistic and nonrelativistic calculations is presented. The factorization of the cross section of the reaction in the impulse approximation is obtained by analytical calculations. It is shown that the photon-neutron interaction plays an important role.

“…The exclusive electrodisintegration of the deuteron is a useful instrument which makes it possible to investigate the electromagnetic structure not only of the bound state -deuteron but also the scattering states of the neutron-proton (np) system. Many approaches have been elaborated to describe this reaction for the last 40 years [1,2,3,4,5]. The simplest of them considered the electrodisintegration within a nonrelativistic model of the nucleon-nucleon (NN) interaction and outgoing nucleons were supposed to be free [1] (the plane-wave approximation -PWA).…”

The exclusive electrodisintegration of the deuteron is considered within the Bethe-Salpeter approach with a separable interaction kernel. The relativistic kernel of nucleon-nucleon interaction is obtained considering the phase shifts in the elastic neutron-proton scattering and properties of the deuteron. The differential cross section is calculated within the impulse approximation under several kinematic conditions of the Bonn experiment. Final state interactions between the outgoing nucleons are taken into account. Partial-wave states of the neutron-proton pair with total angular momentum J = 0, 1 are considered.

“…The experiments were done on the elastic scattering of unpolarized electrons by the tensor polarized deuteron target and also on the measurement of the tensor polarization of the recoil deuteron (for the purpose to separate the charge and quadrupole deuteron electromagnetic form factors) (for the details see the reviews [15]). To determine the neutron charge electromagnetic form factor G En , several polarization measurements were done for the deuteron electrodisintegration process (see, for example, [16]).…”

The differential cross section and the polarization observables for ∆-isobar production in the deuteron electrodisintegration process, e − + d → e − + ∆ + N , are calculated in a general formalism based on structure functions. The obtained expressions have a general nature, hold for one-photon-exchange, assuming P-invariance of the electromagnetic interaction and the conservation of the hadron electromagnetic current. The dependence of the differential cross section of the e − + d → e − + ∆ + N reaction on the vector and tensor polarizations of the deuteron target with unpolarized and longitudinally polarized electrons is considered. The general dependence of the asymmetries on two of five kinematic variables, the azimuthal angle ϕ and ǫ (linear polarization of the virtual photon) is calculated. A similar analysis is performed for the polarization of the nucleon produced in γ * d → ∆N reaction provided the electron beam is unpolarized or longitudinally polarized. Polarization effects, which are due to the strong ∆N − interaction in the final state are calculated. The photoproduction of the ∆-isobar on the deuteron target has been considered in detail, as a particular case. The differential cross section and various polarization observables have been derived in terms of the reaction amplitudes. The polarization observables due to the linear and circular polarizations of the photon, when the deuteron target is arbitrarily polarized have been derived in terms of the reaction amplitudes. The polarization of the final nucleon is also considered.
