Abstract

We present a comprehensive analysis of deep inelastic scattering from ³He and ³H, focusing in particular on the extraction of the free neutron structure function F₂ⁿ. Nuclear corrections are shown to cancel to within 1--2% for the isospin-weighted ratio of ³He to ³H structure functions, which leads to more than an order of magnitude improvement in the current uncertainty in the neutron to proton ratio F₂ⁿ/F₂^p at large x. Theoretical uncertainties originating from the nuclear wave function, including possible non-nucleonic components, are evaluated. Measurements of the ³He and ³H structure functions will, in addition, determine the magnitude of the EMC effect in all A<~3 nuclei.
