The first antiparticle to be discovered was a positron (an antielectron) in 1932.
The success of electron and antielectron (positron) interpretation of Dirac's nonlinear spinor field wave equation brought with itself a great effort among theoretical physicists in searching new nonlinear field equations.
1932 Carl Anderson discovers the antielectron, or positron, confirming the existence of antimatter (electron-positron pair formation shown above).
(27) Para ser rigurosos, la desintegracion beta puede consistir en la emision de un electron o de un positron (antielectron); en ambos casos el numero atomico (la cantidad de carga del nucleo atomico) cambia en una unidad.
An atom of antihydrogen, or anti-H, consists of a negatively charged antiproton and a positively charged antielectron (a.k.a.
Next, they shot a beam of antiprotons into xenon gas to create antielectrons. In at least one case, an antielectron began orbiting an antiproton and created - briefly - antihydrogen.
These negative-state particles came to be thought of eventually as antiparticles-an antielectron and an antiproton- and it was not difficult to imagine that, just as protons and electrons made up matter, so antiprotons and antielectrons, if they actually existed, would make up antimatter.
ALPHA uses an analogue of a very well known system in physics, the hydrogen atom (one electron orbiting one proton), and testing whether its antimatter twin, antihydrogen (an antielectron orbiting an antiproton), behaves the same.
Yet the next year the antielectron was discovered in cosmic rays.
