Query: Spin Hall effect of light in metallic reflection   We report the first measurement of the Spin Hall Effect of Light (SHEL) on an
air-metal interface. The SHEL is a polarization-dependent out-of-plane shift on
the reflected beam. For the case of metallic reflection with a linearly
polarized incident light, both the spatial and angular variants of the shift
are observed and are maximum for -45/45 deg polarization, but zero for pure s-
and p-polarization. For an incoming beam with circular polarization states
however, only the spatial out-of-plane shift is present.
