title = "Laser-controlled antihydrogen production by two-stage charge exchange",
abstract = "Our ATRAP collaboration has now demonstrated a second technique for antihydrogen ({\=H}) production. Lasers are used for the first time to control the production of {\=H} atoms in our cryogenic apparatus at CERN. As suggested in ref. [2] and first reported in ref. [1], lasers excite a thermal beam of cesium (Cs) atoms to a Rydberg state. In a first charge exchange collision one of these laser-excited Cs atoms (Cs*) and a cold e + produces positronium (Ps). Our measurements at Harvard([3]) and at CERN([1]) confirm CTMC simulations([2]) that the laser-selected binding energy in the Cs atom is preserved by the collision and results in Ps with the selected binding energy. A second charge exchange is between one of these Ps atoms and a trapped {\=p}. {\=H} is produced by this second collision and is expected to again have the same binding energy. One advantage of this technique as discussed in ref. [2] is that the {\=H} produced is expected to be extremely cold, at the temperature of the trapped {\=p}, allowing for possible confinement of the {\=H} atoms in a magnetic trap.",
