The Mourre's method is used to prove the limiting absorption principle for the multiparticle Schrodinger operator under the same assumptions on pair potentials as in a two-particle problem. It is shown that at high energies this principle is valid in broader conditions than on the whole spectral axis. By analogy with the three-particle problem the scattering theory is constructed for the Schrodinger operator with potential which vanishes essentially anisotropically at infinity.
