Annihilation

A process in which a particle meets its corresponding antiparticle and both disappear. The energy appears in some other form, perhaps as a different particle and its antiparticle (and their energy), perhaps as many mesons, perhaps as a single neutral boson. The produced particles may be any combination allowed by conservation of energy and momentum and of all the charge types. ...

Annihilation

Annihilation is defined as `total destruction` or `complete obliteration` of an object; having its root in the Latin nihil (nothing). A literal translation is `to make into nothing`. In physics, the word is used to denote the process that occurs when a subatomic particle collides with its respective antiparticle, such as an electron collidin...

Annihilation

• (n.) The state of being annihilated. • (n.) The act of reducing to nothing, or nonexistence; or the act of destroying the form or combination of parts under which a thing exists, so that the name can no longer be applied to it; as, the annihilation of a corporation.

Annihilation

[Southern Reach Trilogy] Annihilation is a 2014 novel by Jeff VanderMeer. It is the first in a series of three books called the Southern Reach Trilogy. The book describes a team of four (a biologist, an anthropologist, a psychologist, and a surveyor) who set out into an area known as Area X. The area is abandoned and cut off from the rest o...

Annihilation

A process in which a particle meets its corresponding antiparticle and both disappear. Their energy and momentum appears in some other form, producing other particles together with their antiparticles and providing their motion.

annihilation

In nuclear physics, a process in which a particle and its `mirror image` particle called an antiparticle collide and disappear, with the creation of a burst of energy. The energy created is equivalent to the mass of the colliding particles in accordance with the mass–energy equation. For example, an electron and a positron annihilate...

Annihilation

In physics, annihilation is the destruction of a particle and its antiparticle when they collide. The annihilation of an electron with a positron generates two or, very rarely, three photons of annihilation radiation.The annihilation of a nucleon with its antiparticle generates several pions.

annihilation

The process in which the entire mass of two colliding particles, one of matter and one of antimatter, is converted into radiant energy in the form of gamma rays. In the case of a collision between an electron and a positron (anti-electron), which have a combined rest mass of 1.02 MeV, the result is ...

Annihilation

With respect to Radiation Protection , annihilation (radiation) results from the annihilation of two particles of opposite charge. For example, if an Electron and a Positron collide, annihilation radiation, consisting of two Photons of energy 0.551 MeV, will be produced, each moving in a direction opposite to the other.
