We report a measurement of the ion recoil energy in photoionization of laser-cooled atoms. 87Rb,
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 µeV is demonstrated.
Refinement of the technique promises resolution in the range of several neV to be feasible.
