Cancellation of the collisional frequency shift in caesium fountain clocks

K. Szymaniec, W. Chalupczak, E. Tiesinga +3

We have observed that the collisional frequency shift in primary caesium fountain clocks varies with the clock state population composition and, in particular, is zero for a given…
