Charge invariance — refers to the fixed electrostatic potential of a particle, regardless of speed. For example, an electron has a specific rest charge. Accelerate that electron, and the charge remains the same (as opposed to the relativistic mass and energy… … Wikipedia
particle — 1 Particle, bit, mite, smidgen, whit, atom, iota, jot, tittle all mean a very small or insignificant piece or part. Particle is used in reference not only to substances which are actually divisible but to such things as a quality, a state, or a… … New Dictionary of Synonyms
Charge number — or just valance[1] of an ion is the coefficient that, when multiplied by the elementary charge, gives the ion s charge. [2] For example, the charge on a chloride ion, Cl − , is , where e is the elementary charge. This means the charge number for… … Wikipedia
particle accelerator — accelerator (def. 7). [1945 50] * * * Device that accelerates a beam of fast moving, electrically charged atoms (ions) or subatomic particles. Accelerators are used to study the structure of atomic nuclei (see atom) and the nature of subatomic… … Universalium
Charge conservation — In physics, charge conservation is the principle that electric charge can neither be created nor destroyed. The net quantity of electric charge, the amount of positive charge minus the amount of negative charge in the universe, is always… … Wikipedia
Particle beam weapon — A particle beam weapon uses an ultra high energy beam of atoms or electrons (i.e., a particle beam) to damage a material target by hitting it, and thus disrupting its atomic and molecular structure. A particle beam weapon is a type of directed… … Wikipedia
Particle accelerator — Atom smasher redirects here. For other uses, see Atom smasher (disambiguation). A 1960s single stage 2 MeV linear Van de Graaff accelerator, here opened for maintenance A particle accelerator[1] is a device that uses electromagnetic fields to… … Wikipedia
charge conservation — ▪ physics in physics, constancy of the total electric charge in the universe or in any specific chemical or nuclear reaction. The total charge in any closed system never changes, at least within the limits of the most precise observation.… … Universalium
Particle in a spherically symmetric potential — In quantum mechanics, the particle in a spherically symmetric potential describes the dynamics of a particle in a potential which has spherical symmetry. The Hamiltonian for such a system has the form:hat{H} = frac{hat{p}^2}{2m 0} + V(r)where m 0 … Wikipedia
Particle beam — A particle beam is an accelerated stream of charged particles or neutrons (often moving at very near the speed of light) which may be directed by magnets and focused by electrostatic lenses, although they may also be self focusing (see… … Wikipedia
Charge (physics) — This article is about charge in the most general physics sense. For charge as relates to electrical phenomena, see electric charge. For other uses of charge, see Charge (disambiguation). In physics, a charge may refer to one of many different… … Wikipedia
