  Based on the recent experimental observations of the dominance of tensor
interaction in the ~250-600~MeV/c momentum range of nucleons in nuclei, the
existence of two new properties for high-momentum distribution of nucleons in
asymmetric nuclei is suggested. The first property is the approximate scaling
relation between proton and neutron high-momentum distributions weighted by
their relative fractions in the nucleus. The second property is the inverse
proportionality of the strength of the high-momentum distribution of protons
and neutrons to the same relative fractions. Based on these two properties the
high-momentum distribution function for asymmetric nuclei has been modeled and
demonstrated that it describes reasonably well the high-momentum
characteristics of light nuclei. However, the most surprising result is
obtained for neutron rich nuclei with large A, for which a substantial relative
abundance of high-momentum protons as compared to neutrons is predicted. For
example, the model predicts that in Au the relative fraction of protons with
momenta above $k_{F} \sim 260$~MeV/c is 50% more than that of neutrons. Such a
situation may have many implications for different observations in nuclear
physics related to the properties of a proton in neutron rich nuclei.
