Neutron unpolarized structure function F2n(x) from deep inelastic scattering off 3He and 3H

The possibility to safely extract the neutron deep inelastic structure function F n 2 (x) in the range 0 ≤ x ≤ 0.9 from joint measurements of deep inelastic structure functions of 3 He and 3 H is demonstrated. While the nuclear structure effects are relevant, the model dependence in this extraction linked to the N − N interaction is shown to be weak.
