A detailed study of the 4 He longitudinal response function RL(ω, q) is performed at different kinematics, with particular emphasis on the role of three-nucleon forces. The effects shown are the results of an ab initio calculation where the full four-body continuum dynamics is considered via the Lorentz integral transform method. The contributions of the various multipoles to the longitudinal response function are analyzed and integral properties of the response are discussed in addition. The Argonne V18 nucleon-nucleon interaction and two different three-nucleon force models (Urbana IX, Tucson-Melbourne ′ ) are used. At lower momentum transfer (q ≤ 200 MeV/c) three-nucleon forces play an important role. One even finds a dependence of RL on the three-nucleon force model itself with differences up to 10%. Thus a Rosenbluth separation of the inclusive electron scattering cross section of 4 He at low momentum transfer would be of high value in view of a discrimination between different three-nucleon force models.

Abstract. In this contribution we summarize recent results on the longitudinal response function of 4 He. It is intended to give an important contribution to one of the most interesting and much discussed topics in nuclear physics at present, i.e. the nuclear many-body forces. The longitudinal response is considered as a possible observable, involving many body scattering states, sensitive to the three-nucleon force (3NF). Such a sensitivity is predicted by ab initio calculations performed using the Lorentz Integral transform (LIT) method. The kinematics that are more interesting to measure are discussed.

“…Core breakup contributions to both W L and W T are expected to be more sizeable at q>250 MeV/c and ω>25 MeV. Typically data on one nucleon knockout from a free α-particle are available at larger q-values than those considered in fig.2 [22]. An estimate of the core breakup contributions to the W L and W T structure functions for inclusive 6 He(e, e ′ ) can be obtained from this reference for 280 MeV/c < ∼ q < ∼ 720 MeV/c.…”

We investigate inclusive electron scattering reactions on two-neutron halo nuclei in the quasielastic region. Expressions for the cross section and structure functions are given assuming that the halo nucleus can be described as a three-body system (core + n + n). The method is applied to 6 He. We compute cross sections and structure functions, and investigate the kinematic conditions for which the observables are determined either by α-knockout or by halo neutron-knockout. The optimal kinematical domain to disantangle the momentum distributions of the various components of the three-body system (q < ∼ 200 MeV/c and ω < q 2 /2M N + 20 MeV) are explored.
