Research.
In 1995 under the leadership of Professor Walter Oelert, the international group of physicists in the CERN laboratory managed to show that they had obtained experimentally nine atoms of antihydrogen in a particle accelerator. Later research allowed the CERN scientists to collect anti-protons among low-energy positrons until they combine into anti-atoms and store them at very low temperatures.
