摘要：

We report a measurement of the ion recoil energy in photoionization of laser-cooled atoms. Rb-87, cooled in a magneto-optical trap, is two-photon ionized by a pulsed laser. The recoil energy is determined by time-of-flight in a weak electric field. A resolution in the range of 1 mu eV is demonstrated. Refinement of the technique promises resolution in the range of several neV to be feasible. [S1050-2947(97)50112-0].
