The antiparticle of the electron. A positron has the same characteristics as an electron but it has a positive charge instead of a negative one.
the anti-matter partner of the electron. It is identical in all respects to an electron, but it has positive charge.
An elementary particle with a positive electric charge, but in other respects identical with an electron.
The antimatter analog of an electron ( +). Positrons have the same mass as electrons but the opposite charge.
positively charged electron or antielectron.
A positron is the anti-matter counterpart of the electron. It has the same mass as an electron, but it has a positive charge. If a positron and an electron meet each other, they annihilate to form a photon.
subatomic particle identical to the electron but possessing a positive charge; the antiparticle of the electron.
A subatomic particle with the same mass as the electron, but with a positive electrical charge; the antiparticle of the electron.
3/4 The antiparticle of the electron, having the same mass but an equal and opposite charge. It is produced in certain decay processes.
An anti-electron. A particle which is, in almost every way, identical to an electron, save for having a positive charge, instead of a negative one. If a positron and electron collide, they both disappear (annihilate), and gamma-radiation with an energy equal to their rest-mass and kinetic energy will appear.
A positron is the antiparticle of an electron. It is called a positron because instead of having a negative charge it has a positive charge. A positron hasthe same mass but the opposite spin and charge of an electron.
( PAH-SEI-TRAHN ) A MASS EQUIVALENT TO THE WEIGHT OF AN ELECTRON, THAT ORBITS AROUND THE NUCLEUS OF ATOMS, THAT HAS EITHER NO SPIN, OR SPINS IN THE OPPOSITE DIRECTION, TO THAT OF AN ELECTRON AND THEREBY HAS AN EQUAL, BUT POSITIVE CHARGE.

The antiparticle of an electron, having positive charge but being otherwise similar.
A particle that has the same mass as an electron, but that carries a positive charge.
an elementary particle with positive charge; interaction of a positron and an electron results in annihilation

an elementary particle that has the same mass as an electron but the opposite charge
a nuclear particle like an electron, but with a positive charge
a particle much the same as an electron, but with a positive charge
a particle of matter with the same mass as an electron , but opposite charge
a particle that occurs naturally, can be created and directed as part of an active sensor scan by Federation starships and shuttlecraft , can be measured by Federation sensors, and is a basis upon which artificial brains can be constructed
a "positive electron," which has the same mass as an electron but a positive charge
a subatomic particle identical in every way to an electron except for its electric charge
a subatomic particle that is produced when radioactive material decays
a time-reversed electron, e
a positive electron emitted from the nucleus during a nuclear reaction.
particle equal in mass, but opposite in charge, to the electron; a positive charge.
A particle having a mass equal to that of an electron and a charge equal to that of an electron, but positive.
The (positively charged) antiparticle of the electron.
particle equal in mass to the electron and having an equal but positive charge.
Atomic particle with properties identical to those of a negatively charged electron, except for its positive charge. This positron is the antiparticle of the electron. Positrons and electrons annihilate each other when they meet, producing pure energy in the form of gamma rays.
Positron is the antiparticle of the electron. It has the same mass and spin as an electron, and an equal but opposite charge.
a positively charged particle having the same mass and magnitude of charge as the electron and constituting the antiparticle of the electron
The antiparticle of the electron, it is capable of mutual annihilation with an electron. This annihilation produces two low-energy gamma-rays at 511 k eV.
(e+): The antiparticle of the electron.
A positively charged particle located in the nucleus of an atom; has the same weight as an electron.
An electron with a positive rather than negative charge; an antielectron.
An elementary particle with the mass of an electron but charged positively. It is the "anti-electron." It is emitted in some radioactive disintegrations and is formed by the interaction of high-energy gamma-rays with matter.
A Nuclear particle with the mass of an electron but opposite charge.
a subatomic particle with the same mass as an electron but with one unit (e) of positive electric charge; also called beta plus
See beta particle.
An antiparticle whose mass and spin are the same as those of an electron, but with an opposite (positive) electric charge of equal magnitude. In the nucleus of an atom, a proton can be transformed to a neutron via emission of a positron-a process known as beta-plus radioactive decay. SEE ALSO antiparticle; beta decay.
(Or antielectron.) A positively charged subatomic particle with the same mass and charge magnitude as that of the electron. The electron's antiparticle, the positron was first observed in 1932 in cosmic rays by Carl Anderson using a Wilson cloud chamber. Boorse, H. A., and L. Motz, 1966: The World of the Atom, Vol. II, 1261â€“1267. Anderson, C. D., 1961: Amer. J. Phys., 29, 825â€“830.
The antiparticle of the electron. [ ] [ Close Glossary
The positron is the antiparticle or the antimatter counterpart of the electron. The positron has an electric charge of +1, a spin of 1/2, and the same mass as an electron. When a low-energy positron collides with a low-energy electron, annihilation occurs, resulting in the production of two gamma ray photons (see electron-positron annihilation).
Positron is a video game made for the BBC Micro and Acorn Electron computers by the programmer Gary Partis, first released by Micro Power in 1983.
