Paper Abstract

Using a laser that is frequency-locked to a Fabry-Perot etalon of high finesse and stability, we probed the 5d106s 2S1/2(F equals O, mF equals O) $ARLR 5d96s2 2D5/2 (F equals 2, mF equals O) electric-quadrupole transition of a single laser-cooled 199Hg+ ion stored in a cryogenic radio-frequency ion trap. We observed Fourier-transform limited linewidths as narrow as 6.7 Hz at 282 nm (1.06 X 1015 Hz). The functional form and estimated values of some of the frequency shifts of the 2S1/2 $ARLR 2D5/2 clock transition (including the quadrupole shift), which have been calculated using a combination of measured atomic parameters and ab initio calculations, are given.
