This research program focuses on the measurement of differential s-wave scattering phase shifts to determine cold collision cross-sections for the cesium atom. The measurement relies on the technique of juggling atoms in a laser-cooled fountain clock to avoid the necessity of determining atom densities. Accuracies better than 10 mrad are anticipated.

这项研究计划集中在测量差分S波散射相移，以确定铯原子的冷碰撞截面。这项测量依赖于在激光冷却喷泉钟中摆弄原子的技术，以避免确定原子密度的必要性。预计测量精度将优于10mrad。
