Positron in a sentence

Bob's positron "knows" that Alice's electron has been measured, and its z-spin detected, and hence B's z-spin has been calculated, but the x-spin of Bob's positron remains uncertain.

Gamma rays, emitted indirectly by a positron-emitting radionuclide (tracer), are detected in positron emission tomography (PET) scanners used in hospitals.

Schema of a PET acquisition process As the radioisotope undergoes positron emission decay (also known as positive beta decay ), it emits a positron, an antiparticle of the electron with opposite charge.

When a low-energy positron collides with a low-energy electron, annihilation occurs, resulting in the production of two or more gamma ray photons (see electron–positron annihilation ).

Finally, positron torpedoes only appear in Star Trek: Bridge Commander.

Positron has lower revenue, but higher earnings than Tivic Health Systems.

Project would debut with electron-positron collider at cost of roughly $10.

The couple researched the projection of nuclei, which was an essential step in the discovery of the neutron and the positron.

An international team of researchers made beams from a special kind of plasma (a gas where the charged particles are separated and not confined to atoms), called an electron-positron plasma.

Once the antihydrogen ions have been trapped and cooled down significantly to 10 microkelvin, laser light will be utilized to take away one positron, which will, in effect, change them into neutral antiatoms.

This report also studies the global Positron Emission Tomography (PET) Scanners market status, competition landscape, market share, growth rate, future trends, market drivers, opportunities and challenges, sales channels and distributors.

After 15 seconds had passed, however, the temperature of the universe dropped below the threshold where electron-positron formation could occur.

Also observed, for charged pions only, is the very rare "pion beta decay " (with branching fraction of about 10 −8 ) into a neutral pion, an electron and an electron antineutrino (or for positive pions, a neutral pion, a positron, and electron neutrino).

An unfilled state in the Fermi sea behaves like a positively charged electron, though it is referred to as a "hole" rather than a "positron".

A photon can also be emitted when a particle and its corresponding antiparticle are annihilated (for example, electron–positron annihilation ).

A positron (e + )—an antimatter electron—is emitted along with an electron neutrino The number of protons and neutrons in the atomic nucleus can be modified, although this can require very high energies because of the strong force.

At the Jülich Institute of Neurosciences and Biophysics, the world's largest PET-MRI device began operation in April 2009: a 9.4- tesla magnetic resonance tomograph (MRT) combined with a positron emission tomograph (PET).

Because charge must be conserved, one of the products of muon decay is always an electron of the same charge as the muon (a positron if it is a positive muon).

Because it is in a superposition of states it is impossible without measuring to know the definite state of spin of either particle in the spin singlet. citation : 421–422 The EPR thought experiment, performed with electron–positron pairs.

Changing of regional blood flow in various anatomic structures (as a measure of the injected positron emitter) can be visualized and relatively quantified with a PET scan.
