Abstract :
Preliminary measurements of the cold collision frequency shift in /sup 87/Rb fountain clocks have shown it to be much smaller than that in a Cs fountain. We will report our measurement of the cold collision shift in /sup 87/Rb, and on progress towards achieving high short-term stability in our Rb fountain.
