![]() The experiment involves shining a laser beam on trapped antihydrogen atoms, which can absorb the light only at very specific frequencies. ![]() “We are thrilled and relieved that we finally achieved what we set out to do when we started up in 2004, not least because ALPHA stands for Antihydrogen Laser Physics Apparatus!” Makoto Fujiwara, TRIUMF Research Scientist and spokesperson for the ALPHA-Canada collaboration. “Laser measurement on antimatter atoms has been a dream in the field for decades,” said an enthusiastic Dr. Their latest work represents a major step towards developing a very precise test of whether antimatter behaves differently than its normal matter anti-twin, thus opening up a promising new front to address the basic antimatter question: “if matter and antimatter were created equally during the Big Bang, where is all the antimatter?” ALPHA is an international team of researchers, including the ALPHA-Canada group, which studies antihydrogen, the antimatter partner to hydrogen. Released today in the prestigious journal Nature, the collaboration reports on the first spectroscopic measurement of an atom of antimatter using lasers. ![]() Newswise - Vancouver, Canada – Another year, another scientific breakthrough, and the latest from the ALPHA Collaboration could be its most important yet.
