Abstract

We compare the frequencies of two single ion frequency standards: 27Al+ and 199Hg+. Systematic fractional frequency uncertainties of both standards are below 10-16, and the statistical measurement uncertainty is below 5 × 10 -17. Recent ratio measurements show a reproducibility that is better than 10-16.
