“…Finally, we would like to mention that polarization observables have been studied in the two-body case, both in the conventional approach (see, e.g., [21,230]) and in the χEFT approach (see, e.g., [226]), where important effects of exchange currents have been found. 4.1.2.…”

Abstract. Electromagnetic reactions on light nuclei are fundamental to advance our understanding of nuclear structure and dynamics.The perturbative nature of the electromagnetic probes allows to clearly connect measured cross sections with the calculated structure properties of nuclear targets. We present an overview on recent theoretical abinitio calculations of electron-scattering and photonuclear reactions involving light nuclei. We encompass both the conventional approach and the novel theoretical framework provided by chiral effective field theories. Because both strong and electromagnetic interactions are involved in the processes under study, comparison with available experimental data provides stringent constraints on both many-body nuclear Hamiltonians and electromagnetic currents. We discuss what we have learned from studies on electromagnetic observables of light nuclei, starting from the deuteron and reaching up to nuclear systems with mass number A = 16.

“…The comparison with data is very good, at least within the non relativistic regime (see e.g. [16,17]). As to category B potentials, analogous systematic studies are still missing.…”

Test ofJ-matrix inverse scattering potentials on electromagnetic reactions of few-nucleon systems

The J-matrix inverse scattering nucleon-nucleon potentials (JISP), describing both two-nucleon data and bound and resonant states of light nuclei to high accuracy, are tested on the total photoabsorption cross sections of 2 H, 3 H and 3,4 He. The calculations in the three-and four-body systems are carried out via the Lorentz integral transform method and the hyperspherical harmonics (HH) technique. To this end the HH formalism has been adapted to accommodate non-local potentials.The cross sections calculated with the JISP are compared to those obtained with more traditional realistic interactions, which include two-and three-nucleon forces. While the results of the two kinds of potential models do not differ significantly at lower energies, beyond the resonance peak they show fairly large discrepancies, which increase with the nuclear mass. We argue that these discrepancies may be due to a probably incorrect long range behavior of the JISP, since the one pion exchange is not manifestly implemented there.
