Polarization observables in inclusive and exclusive electrodisintegration of the deuteron using a polarized beam and an oriented target are systematically surveyed using the standard nonrelativistic framework of nuclear theory but with leading order relativistic contributions included. The structure functions and the asymmetries corresponding to the various nucleon polarization components are studied in a variety of kinematic regions with respect to their sensitivity to realistic N N -potential models, to subnuclear degrees of freedom in terms of meson exchange currents, isobar configurations and to relativistic effects in different kinematical regions, serving as a benchmark for a test of present standard nuclear theory with effective degrees of freedom.

“…Deuteron electro-disintegration has been employed as a testing ground for NN models for a long time [17][18][19][20][21][22]. Since the 4-momentum in the breakup process is given by a virtual photon, a richer set of kinematics can be probed as compared to the photo-disintegration process.…”

We use chiral effective field theory (χEFT) to make predictions for the longitudinal electromagnetic response function of the deuteron, f L , which is measured in d(e, e ′ N ) reactions. In this case the impulse approximation gives the full χEFT result up to corrections that are of O(P 4 ) relative to leading order. By varying the cutoff in the χEFT calculation between 0.6 and 1 GeV we conclude that the calculation is accurate to better than 10% for values of q 2 within 4 fm −2 of the quasi-free peak, up to final-state energies E np = 60 MeV. In these regions χEFT is in reasonable agreement with predictions for f L obtained using the Bonn potential. We also find good agreement with existing experimental data on f L , albeit in a more restricted kinematic domain.

“…Apart from the general approach of [2], research on these reactions has only been performed for light nuclei. In particular, it is worth mentioning the systematic research on general sets of spin observables for deuterium performed in the last decade by Arenhö vel et al [33][34][35][36][37][38]. In the present paper we try to fill this gap and begin an exploration of the new spin observables that arise in these exclusive reactions from medium nuclei.…”

Skewed recoil polarization in (e,e′p) reactions from polarized nuclei

The general formalism describingÃðẽ; e 0p ÞB reactions, involving polarization of the electron beam, target, and ejected proton, is presented within the framework of the relativistic plane wave impulse approximation for medium and heavy nuclei. It is shown that the simultaneous measurement of the target and ejected proton polarization can provide new information which is not contained in the separate analysis of theÃðẽ; e 0 pÞB and Aðẽ; e 0p ÞB reactions. The polarization transfer mechanism in which the electron interacts with the initial nucleon carrying the target polarization, making the proton exit with a fractional polarization in a different direction, is referred to here as ''skewed polarization.'' The new observables characterizing the process are identified, and written in terms of polarized response functions and asymmetries which are of tensor nature. The corresponding half-off-shell single-nucleon responses are analyzed using different prescriptions for the electromagnetic vertex and for different kinematics. Numerical predictions are presented for selected perpendicular and parallel kinematics in the case of 39 K as polarized target.
