First Laser-Controlled Antihydrogen Production
2004
Physical Review Letters
Lasers are used for the first time to control the production of antihydrogen (H). Sequential, resonant charge exchange collisions are involved in a method that is very different than the only other method used so far-producing slow H during positron cooling of antiprotons in a nested Penning trap. Two attractive features are that the laser frequencies determine the H binding energy, and that the production of extremely cold H should be possible in principle -likely close to what is needed for
