Backward Elastic p^3He-Scattering and High Momentum components of ^3He Wave Function

Abstract

It is shown that owing to a dominance of $np-$pair transfer mechanism of backward elastic $p^{3}He$- 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 ${}^{3}He$ nucleus, ${\varphi }^{23}({\mathbf{q}}_{23},{\mathbf{p}}_1)$, at high relative momenta $q_{23}>0.6GeV/c$ of the NN-pair in the ${}^1{S}_0-$ state and at low spectator momenta $p_1\sim 0-0.2$ GeV/c.
