    "abstract": "Backward elastic $p ^3He$-scattering at incident proton kinetic energies\n$T_p\u003e1$ GeV is investigated in the framework of the np-pair transfer mechanism\nand triangular diagram of one-pion exchange with a subprocess $pd\\to ^3He\\pi^0$\nusing a realistic three-body wave function of the $^3He$ nucleus.\n  It is found that the $np-$pair transfer mechanism dominates owing to a rich\nhigh momentum component of the $^3He$ wave function.\n  We show that the experimental cross section of this process is defined mainly\nby the values of the Faddeev component of the $^3He$ wave function, $\\phi\n^{23}({\\bf q}_{23}, {\\bf p}_1)$, at high relative momenta $q_{23}\u003e 0.6 GeV/c$\nof the NN-pair in the $^1S_0$-state and at low spectator momenta $p_1\\leq 0.1$\nGeV/c. The spin-spin correlation parameter is calculated in the framework of\nthe dominating mechanism for the case of polarized target and beam.\nRescatterings in the initial and final states are taken into account.\nComparison with the $pd\\to dp$ process is performed.",
