Molecules of Positronium Observed in the Laboratory for the First Time
September 12, 2007
Physicists at University of California-Riverside, have created molecular positronium, an entirely new object in the laboratory. Briefly stable, each molecule is made up of a pair of electrons and a pair of positrons. David Cassidy and Allen Mills made the molecules by firing positrons into a film of porous silica. The research paves the way for studying multi-positronium interactions and could one day help develop fusion power generation and directed energy weapons such as gamma-ray lasers.
