AbstractTo prepare cold lithium atoms for atomic interferometry experiments, we have carried out experimental researches on Zeeman deceleration and magneto-optical trap (MOT) of lithium atoms. We have also designed and implemented a compact adjustable Zeeman slower with an inner water cooling chamber, to decelerate the velocity of the Li-7 atom beam from 600 m/s down to 60 m/s, and load them into the MOT. The loading rate is 5 x 10(8) /s, the total trapped atom number is 1 x 10(9), and the lowest temperature of the atom cloud is 220 +/- 30 mu K. Then we investigate the dependence of lifetime of Li-7 atoms in optical molasses on the detuning of trapping laser beams. The above results lay a foundation for further sub-Doppler cooling, optical trap based on evaporative cooling, and atomic interferometry experiments.
