We have observed resonant energy transfer between cold Rydberg atoms in spatially separated cylinders. Resonant dipole-dipole coupling excites the 49s atoms in one cylinder to the 49p state while the 41d atoms in the second cylinder are transferred down to the 42p state. We have measured the production of the 49p state as a function of separation of the cylinders (0-80 microm) and the interaction time (0-25 micros). In addition, we measured the width of the electric field resonances. A full many-body quantum calculation reproduces the main features of the experiments.
我们观测到了空间分离圆柱中冷里德堡原子之间的共振能量转移。共振偶极-偶极耦合将一个圆柱中的49s原子激发到49p态，而第二个圆柱中的41d原子则跃迁到42p态。我们测量了49p态的产生与圆柱间距（0 - 80微米）和相互作用时间（0 - 25微秒）的函数关系。此外，我们还测量了电场共振的宽度。一个完整的多体量子计算再现了实验的主要特征。
