Positronium (Ps) is an exotic atom consisting of an electron (e⁻) bound to its antiparticle, the the positron's (e⁺), by the Coulomb force. It has a structure similar to the hydrogen atom but contains a positron instead of a proton. This composition makes Ps a unique model for studying particle-antiparticle systems.The existence of positronium was first predicted theoretically by Mohorovičić in 1934. Its spectroscopic structure was calculated by Ruark in 1945, and its binding energy and lifetime

Antimatter is a type of matter composed of antiparticles, each of which has the same mass as the fundamental particles in the universe but opposite electric charge. In the context of modern physics, antimatter can be described as the mirror image of matter. The antiparticle of the electron is the positron, that of the proton is the antiproton, and that of the neutron is the antineutron. When antimatter comes into contact with matter, it transforms into energy through a process known as annihilat
