The antimatter equivalent of an electron, having the same mass but a positive charge
The anti-particle of an electron, having a positive charge instead of the more usual negative charge It is the only anti-particle of significance in the context of nuclear power Pressure Vessel A reactor containment vessel, usually made from thick steel or pre-stressed concrete, capable of withstanding high internal pressure Used in gas-cooled reactors and light water reactors Proton A stable elementary particle with a charge of 1 6 x 10-19 Coulomb and a mass of 1 67 x 10-27 kg (1 atomic mass unit) The proton forms the whole nucleus of hydrogen atoms of mass number 1 and a part of all other nuclides The number of protons in a nucleus of any element is the atomic number (Z) of that element
The antimatter analog of an electron ( +) Positrons have the same mass as electrons but the opposite charge
A particle emitted from some radioactive nuclei that is positively charged but otherwise identical with the electron
The (positively charged) antiparticle of the electron
– a subatomic particle with the same mass as an electron but with one unit (e) of positive electric charge; also called beta plus
an elementary particle with positive charge; interaction of a positron and an electron results in annihilation
A Nuclear particle with the mass of an electron but opposite charge
Particle equal in mass to the electron and having an equal but opposite charge
(e+): The antiparticle of the electron
An Anti-electon The positively-charged antiparticle of anelectron
positively charged electron or antielectron
an atomic particle with the same mass as an electron but with one unit of positive charge
The antiparticle of the electron, it is capable of mutual annihilation with an electron This annihilation produces two low-energy gamma-rays at 511 keV
A subatomic particle which is identical to the electron in atomic mass, theoretical rest mass, and energy, but opposite in sign Compare proton
a positive electron emitted from the nucleus during a nuclear reaction
A particle which has the same weight and charge as an electron but is electrically positive rather than negative The positron's existence was predicted in theory years before it was actually detected It is not stable in matter
a very small piece of matter that has the same mass as an electron but has a positive electrical charge (positive + -tron (as in electron)). Subatomic particle having the same mass as an electron but with an electric charge of +1 (an electron has a charge of -1). It constitutes the antiparticle (see antimatter) of an electron. The existence of the positron was a consequence of the electron theory of P. A. M. Dirac (1928), and the particle was discovered in cosmic rays by Carl D. Anderson (1905-1991) in 1932. Though they are stable in a vacuum, positrons react quickly with the electrons of ordinary matter, producing gamma rays by the process of annihilation. They are emitted in positive beta decay of proton-rich radioactive nuclei and are formed in pair production
An Anti-electron The positively-charged antiparticle of an electron
particle equal in mass to the electron and having an equal but positive charge
an antiparticle of an electron
Atomic particle with properties identical to those of a negatively charged electron, except for its positive charge The positron is the antiparticle of the electron Positrons and electrons annihilate one another when they meet, producing pure energy in the form of gamma rays
Antiparticle of the electrons More Information: Leptons, Positron Electron Project (PEP) Experiment
{i} antiparticle of an electron, elementary particle equal in mass to the electron but with a positive electrical charge (Physics)

positron emission tomography
A medical imaging technique which detects the gamma rays produced by positrons emitted from injected radionuclides
Positron Emission Tomography
technique for creating detailed images of bodily tissues by injecting positron-laden material into the body and recording the gamma rays emitted over a period of about two hours (Medicine)
positron emission tomography
Tomography in which a computer-generated image of a biological activity within the body is produced through the detection of gamma rays that are emitted when introduced radionuclides decay and release positrons. Imaging technique used in diagnosis and biomedical research. A chemical compound labeled with a radioactive isotope (see radioactivity) that emits positrons is injected into the body, and detectors measure their activity in the tissues as they combine with electrons and are annihilated. Computers analyze, integrate, and reconstruct the data to produce images of the organs scanned. PET is particularly useful for studying brain and heart functions
positron emission tomography
using a computerized radiographic technique to examine the metabolic activity in various tissues (especially in the brain)
positron emission tomography scanner
a tomograph that produces cross-sectional X-rays of metabolic processes in the body
