Cold Collision Frequency Shifts in a 87Rb Atomic Fountain
Y Sortais, S Bize, C Nicolas, A Clairon, C Salomon, C Williams
We present measurements of cavity frequency pulling and collisional frequency shifts in a 87Rb fountain with a frequency resolution of 3 x 10-16. Agreement with theory is found for the cavity pulling and the measured collisional shifts. The clock shift is found at least 50 times smaller than in 133Cs.
