Laser Breakthrough Has Physicists Close To Cooling Down Antimatter
Laser breakthrough has physicists close to cooling down antimatter For the first time, physicists at CERN have observed a benchmark atomic energy transition in anithydrogen, a major step toward cooling and manipulating the basic form of antimatter. "The Lyman-alpha transition is the most basic, important transition in regular hydrogen atoms, and to capture the same phenomenon in antihydrogen opens up a new abad in antimatter science," said Takamasa Momose, the University of British Columbia chemist and physicist who led the development of the laser system used to manipulate the anithydrogen. "This approach is a gateway to cooling down antihydrogen, which will greatly improve the precision of our measurements and allow us test how antimatter and gravity interact, which is still a mystery." The results were published today in Nature . Antimatter, annihilated on impact with matter, is notoriously tricky to capture and work with. But its study is key...
