本文报道了钾原子的玻色-爱因斯坦凝聚，其中的量子简并是通过与蒸发冷却的铷的共振冷却来实现的。由于两个不同原子的快速热化，冷却过程的效率很高。通过与不同物种的交感冷却实现冷凝的能力可以提供一种生产具有更大组分选择的简并系统的途径。
We report on the Bose-Einstein condensation of potassium atoms, whereby quantum degeneracy is achieved by sympathetic cooling with evaporativety cooled rubidium. Because of the rapid thermalization of the two different atoms, the efficiency of the cooling process is high. The ability to achieve condensation by sympathetic cooling with a different species may provide a route to the production of degenerate systems with a larger choice of components.
