摘要：

We present measurements of cavity frequency pulling and collisional frequency shifts in a Rb-87 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 Cs-133.
