Inclusive quasielastic electron scattering on He-6: a probe of the halo structure

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