Relating F2p(x), F2n(x) and F2D(x) using a relativistic description of the deuteron structure

We propose a practical procedure relating the proton, neutron and deuteron structure functions, which allows one to avoid appreciable theoretical ambiguites, which are present in other analyses largerly due to simplifications in the treatment of Fermi motion. The suggested rigorous consideration is shown to be important in a wide interval of x and not only in the high x range.
