    "abstract": "We present a solution to the problem of reflection/refraction of a polarized\nGaussian beam on the interface between two transparent media. The transverse\nshifts of the beams\u0027 centers of gravity are calculated. They always satisfy the\ntotal angular momentum conservation law for beams, however, in general, do not\nsatisfy the conservation laws for individual photons in consequence of the lack\nof the ``which path\u0027\u0027 information in a two-channel wave scattering. The field\nstructure for the reflected/refracted beam is analyzed. In the scattering of a\nlinearly-polarized beam, photons of opposite helicities are accumulated at the\nopposite edges of the beam: this is the spin Hall effect for photons, which can\nbe registered in the cross-polarized component of the scattered beam.",
