Query: Model independent method for determination of the DIS structure of free
  neutron   We present a model independent procedure for extracting deep-inelastic
structure function of "free'' neutron from the electron - deuteron scattering
with protons produced in the target fragmentation region of the reaction. This
procedure is based on the extrapolation of t, which describes the invariant
momentum transfered to the proton, to the unphysical region corresponding to
the mass of the struck neutron. We demonstrate that the impulse approximation
diagram of the reaction has a pole at this limit with a residue being
proportional to the "free" neutron structure function. The method is analogous
to that of Chew and Low for extraction of the ``free'' pion-pion and
neutron-neutron cross sections from p(pion,p)X and d(n,n)pn reactions
respectively. We demonstrate that in the extrapolation the final state
interaction amplitudes are smooth functions of $t$ and have negligible
contribution in the extracted ``free'' nucleon structure function. We also
estimate the range of the recoil nucleon momenta which could be used for
successful extrapolation procedure.
