Walter OelertWalter Oelert was a professor at the Juelich Research Center in Germany.ResearchIn 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.
