Abstract
We report an experiment on recoil-ion momentum spectroscopy of ions formed by two-photon ionization of at 790 nm. Laser-cooled atoms in a magneto-optic trap are used as the target in time-of-flight analysis of the recoil momentum. We demonstrate a resolution of 1 μeV with a limiting momentum resolution below a.u. We also show the use of the photoionization technique for the characterization of cold atomic samples.
