We present details on the ultraviolet lattice spectroscopy of the (6s2) 1S0↔(6s6p) 3P0 transition in neutral mercury, specifically 199Hg. Mercury atoms are loaded into a one-dimensional vertically aligned optical lattice from a magneto-optical trap with an rms temperature of ∼60 μK. We describe aspects of the magneto-optical trapping, the lattice cavity design, and the techniques employed to trap and detect mercury in an optical lattice. The clock-line frequency dependence on lattice depth is measured at a range of lattice wavelengths. We confirm the magic wavelength to be 362.51(0.16) nm. Further observations to those reported by Yi are presented regarding the laser excitation of a Wannier-Stark ladder of states.
