Particle decay — is the spontaneous process of one elementary particle transforming into other elementary particles. During this process, an elementary particle becomes a different particle with less mass and an intermediate particle such as W boson in muon decay … Wikipedia
Particle therapy — Intervention ICD 9: 92.26 Particle therapy is a form of external beam radiotherapy using beams of energetic protons, neutrons, or positive ions for cancer treatment. The most common … Wikipedia
Particle radiation — is the radiation of energy by means of fast moving subatomic particles. Particle radiation is referred to as a particle beam if the particles are all moving in the same direction, similar to a light beam.Due to the wave particle duality, all… … Wikipedia
Particle — may refer to:In chemistry: * Colloidal particle, part of a one phase system of two or more componentsIn physics: * Subatomic particle, which may be either: **Elementary particle, a particle of which larger particles are composed, also called a… … Wikipedia
Particle identification — is the process of using information left by a particle passing through a particle detector to identify the type of particle. Particle identification reduces backgrounds and improves measurement resolutions, and is essential to many analyses at… … 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
Particle system — The term particle system refers to a computer graphics technique to simulate certain fuzzy phenomena, which are otherwise very hard to reproduce with conventional rendering techniques. Examples of such phenomena which are commonly replicated… … Wikipedia
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 velocity level — The particle velocity level or the sound velocity level tells the ratio of a sound incidence in comparison to a reference level of 0 dB in a medium, mostly air.It shows the ratio of the particle velocity v 1 and the particle velocity v 0.The… … Wikipedia
Particle acceleration — In a compressible sound transmission medium mainly air air particles get an accelerated motion: the particle acceleration or sound acceleration with the symbol a in metre/second sup2;. In acoustics or physics, acceleration (symbol: a ) is defined … Wikipedia
particle flux unit — (pfu) a unit used to measure the rate at which energetic particles, such as protons, are received by spacecraft. These flux rates are a major component of the space weather, the environment in which satellites and other spacecraft operate. One … Dictionary of units of measurement
