Abstract
The compare the frequency of the /sup 171/Yb/sup +/ 12.6 GHz M/sub F/=0/spl rarr/0 ground state hyperfine 'clock' transition in buffer gas-cooled ion clouds confined in two similar, but not identical, lineal Paul traps. After correction for the known differences between the two ion traps, including significantly different second-order Doppler shifts, the frequencies agree within an uncertainty of less than 2 parts in 10/sup 13/. The frequency of the clock transition in an isolated ion at zero temperature, velocity, electric field and magnetic field, was found to be 12 642 812 118.468/spl plusmn/0.0016 Hz.
