Abstract

A technique to cancel the frequency shift due to cold collisions of laser-cooled atoms is proposed. Results for future clocks based on Cs135 and Cs137 are presented. We find a Cs137 fountain clock can be operated with no cold-collision shift by adjusting the population ratios in the fountain, and it may also be possible for Cs135. This technique can also be applied to other phase-sensitive measurements using cold atoms, including atom interferometers.
