摘要：

We report a measurement of the quadratic collisional loss rate coefficient beta of a Li-7 trap as a function of the trap potential in a range covering the energy of the fine-structure splitting P-2(3/2)-P-2(1/2). The value of beta decreases an order of magnitude when the trap potential is increased beyond 0.24 K, and reaches the minimum value of 3 X 10(-13) cm3 s-1 at 0.45 K. At a higher trap potential the beta increases proportionally to the trap potential.
