The existence of wave operators is considered for SCHRÖDINGER operators with anisotropic potentials. The potentials may have positive barriers which are allowed to increase up to infinity over unbounded regions in R n . The convergence of the corresponding wave and scattering operators is shown. In the time‐dependent geometric proofs the FEYNMAN‐KAC‐formula is applied essentially.
