Query: Backward Elastic p^3He-Scattering and High Momentum components of ^3He
  Wave Function   It is shown that owing to a dominance of $np-$pair transfer mechanism of
backward elastic $p^3He$- scattering for incident proton kinetic energies
$T_p>1$ GeV the cross section of this process is defined mainly by the values
of the Faddeev component of the wave function of $^3He$ nucleus, $\phi
^{23}({\bf q}_{23}, {\bf p}_1)$, at high relative momenta $q_{23}> 0.6 GeV/c$
of the NN-pair in the $^1S_0-$ state and at low spectator momenta $p_1\sim
0-0.2$ GeV/c.
