The positron or antielectron is the particle with an electric charge of +1e, a spin of 1/2 (the same as the electron), and the same mass as an electron...

Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes...

neutron while releasing a positron and an electron neutrino (νe). Positron emission is mediated by the weak force. The positron is a type of beta particle...

Look up Positron, positron, positrón, or pósitron in Wiktionary, the free dictionary. A positron is an elementary particle of antimatter. Positron may also...

positron, a muon and an antimuon, or a proton and an antiproton. Pair production often refers specifically to a photon creating an electron–positron pair...

Electron–positron annihilation occurs when an electron ( e− ) and a positron ( e+ , the electron's antiparticle) collide. At low energies, the result...

component of widely available applications related to beta decay, such as positron emission tomography, radiation therapy, and industrial imaging. In theory...

Positron Corporation is an American nuclear medicine healthcare company specializing in cardiac Positron Emission Tomography (PET) imaging. Positron is...

which an atomic nucleus emits a beta particle (fast energetic electron or positron), transforming into an isobar of that nuclide. For example, beta decay...

or beta radiation (symbol β), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process...
