在精细结构分裂2 P3/2 - 2 P1/2能量范围内，测量了7 Li陷阱的二次碰撞损失率系数β与陷阱势的关系.当陷阱势增大到0.24K以上时，β值减小一个数量级，并在0.45K时达到最小值3×10 - 13 cm 3s-1。在较高的陷阱电位下，β与陷阱电位成比例地增加
We report a measurement of the quadratic collisional loss rate coefficient β of a 7 Li trap as a function of the trap potential in a range covering the energy of the fine-structure splitting 2 P 3/2 - 2 P 1/2 . The value of β decreases an order of magnitude when the trap potential is increased beyond 0.24 K, and reaches the minimum value of 3×10 -13 cm 3 s -1 at 0.45 K. At a higher trap potential the β increases proportionally to the trap potential
