Electron and positron annihilate
WebSep 6, 2014 · So an electron and its anti-particle (the positron), which have spin-1/2 can be combined to produce angular momentum 0, 1, 2, etc. Two photons, each of which have spin-1, can be combined to produce angular momentum 0, 1, 2, etc. So an electron and a positron can collide to produce two photons. WebA few of the weak interactions make sense. An electron and a positron can annihilate to form a Z boson. Similarly, any standard model fermion and its antiparticle can annihilate to form a Z. An electron and an electron anti-neutrino can annihilate to form a W. Similarly, and lepton and the appropriate anti-neutrino can annihilate to form a W.

WebFeb 22, 2024 · A positron of mass \(m\) and kinetic energy equal to its mass strikes an electron at rest. They annihilate, creating two high-energy photons. They annihilate, … WebThe most common annihilation on Earth occurs between an electron and its antiparticle, a positron. A positron, which may originate in radioactive decay or, more commonly, in the interactions of cosmic rays in matter, usually combines briefly with an electron to form a quasi-atom called positronium.
Weba process in whi ch an electron and a positron annihilate one another. The converse process, namely the creation of an electron and a positron from electromagnetic radiation, should also be able to take place. Such processes appear to have been found experimentally, and are at present being more closely investigated by experimenters.
WebFeb 22, 2024 · A positron is the antimatter partner of an electron. It has exactly the same mass as an electron but has the opposite electric charge. When kept separate from matter, positrons can exist forever. However, when a positron meets an electron, the two particles annihilate into a flash of energy.
