Physicists at CERN have produced a beam of antihydrogen atoms, moving researchers closer to unlocking the mysteries of antimatter. "Our results are very promising for high-precision studies of antihydrogen atoms, particularly the hyperfine structure, one of the two best known spectroscopic properties of hydrogen," said RIKEN's Yasunori Yamazaki, team leader of the Atomic Spectroscopy and Collisions Using Slow Antiprotons experiment. "Its measurement in antihydrogen will allow the most sensitive test of matter/antimatter symmetry. We are looking forward to restarting this summer with an even more improved set-up."
