Effect of quark exchange on the structure function of = 3 mirror nuclei and neutron/proton structure function ratio

摘要

By using quark-exchange formalism and realistic Faddeev wave functions, we investigate deep inelastic electron scattering from = 3 mirror nuclei. The initial valence quarks input are taken from the GRV's calculations on F(x, Q2) which gives very good fit to the available data in the (x, Q2)-plane. It is shown that the free neutron to proton structure functions ratio can be extracted from corresponding EMC ratios for 3He and 3H mirror nuclei. The results are in good agreement with other theoretical models as well as present available experimental data.
