Abstract
We study the effects of the ballistic expansion of an atomic cloud on theoretical predictions of the collisional shifts in the Cesium atomic fountain clock. Due to the strong energy dependence of the collisional shift, we find that the ballistic expansion is important and consequently the calculated collisional clock shifts are sensitive to the atomic density and distribution of velocities of the initial atomic cloud.Citation
