Abstract

The cold collision shifts for Rb clocks is calculated. For Rb, the fractional cold collision frequency shift is expected to be 15 times smaller than that for Cs. For Rb, the frequency shifts produced by the populations in the two clock states have opposite signs. This implies that, by adjusting the population ratios in the clock, it is possible to accurately eliminate the cold collision frequency shift. Because the Rb transition frequency of 3.035 GHz is three times smaller than that of Cs, Rb is much better suited for space-based laser-cooled clocks than for earth-based fountains.
