“…We conclude that ∆ degrees of freedom should be of greater importance for the 3 He(e, e ′ pp) and 3 He(e, e ′ pn) reactions in the dip region. Here it is worthwhile mentioning that recently the reaction 3 He(e, e ′ pn) has been studied in the dip region for various momentum transfers q ranging from 300 to 450 MeV/c [10]. Rather large differences were found between experimental and theoretical results, but neither a 3NF nor ∆-IC were included in the theoretical calculation.…”

The 3 He transverse electron scattering response function RT (q, ω) is calculated in the quasi-elastic peak region and beyond for momentum transfers q = 500, 600 and 700 MeV/c. Distinct from our previous work for these kinematics where we included meson exchange currents and relativistic corrections we now additionally include ∆ isobar currents (∆-IC). The ∆-IC contribution increases the quasi-elastic peak height by about 5% and leads to an excellent agreement with experimental data in the whole peak region. In addition it is shown that effects due to the three-nucleon force largely cancel those due to the ∆-IC in the peak region. Finally, we have found that ∆-IC are important for three-body break-up reactions in the so-called dip region. This could explain why in a previous study of such a reaction, where ∆ degrees of freedom were not included, no agreement between experimental and theoretical results could be obtained.

“…At Mainz, the 3 He(e,e'pn)p cross section has recently been measured and again shows the dominance of the proton-nucleon reaction (tensor-correlations) in the momentum range above the Fermi momentum [20]. Interestingly, the Faddeev calculations using AV-18 or Bonn-B nucleon-nucleon potentials over-estimate the magnitude of the 3 He(e,e'pn)p cross section at low missing momentum.…”

Abstract. Recent cross section (e,e'pN) short-range correlation experiments have clearly shown the strong dominance of tensor correlations for (e,e'p) missing momenta greater than the Fermi momentum; while recent 2 H(e,e'p)n and 4 He(e,e'p)t asymmetry experiments at low missing momentum have shown small changes from the free nucleon form factor. By doing asymmetry experiments as a function of missing momentum, these results can be linked together and observed as a change of sign in the measured asymmetry. This idea will be presented within the context of the recently completed Jefferson Lab Hall A quasi-elastic, polarized 3 He(e,e'N) experiments (N=0,p,n,d) where the asymmetries of several reaction channels were measured with three, orthogonal target-spin directions. Together, these various experiments will help us to better understand nucleons in the nuclear medium.
