Long term measurement of the ^{87}Sr clock frequency at the limit of primary Cs clocks
We report on a series of 42 measurements of the transition frequency of the 429 THz (5s^{2}) ^{1}S_{0}–(5s5p) ^{3}P_{0} line in ^{87}Sr taken over three years from 2017 to 2019. They were performed at the Physikalisch-Technische Bundesanstalt (PTB) between the laboratory strontium lattice clock and...
