unusual facts about charged particles



Neutron depth profiling

In NDP, a thermal or cold neutron beam passes through a material and interacts with isotopes that emit monoenergetic charged particles upon neutron absorption; either a proton or an alpha, and a recoil nucleus.

Angular momentum coupling

Or two charged particles, each with a well-defined angular momentum, may interact by Coulomb forces, in which case coupling of the two one-particle angular momenta to a total angular momentum is a useful step in the solution of the two-particle Schrödinger equation.

Cherenkov radiation

The Cherenkov radiation from these charged particles is used to determine the source and intensity of the cosmic ray or gamma ray, which is used for example in the Imaging Atmospheric Cherenkov Technique (IACT), by experiments such as VERITAS, H.E.S.S. and MAGIC.

Crookes tube

It was used by Crookes, Johann Hittorf, Julius Plücker, Eugen Goldstein, Heinrich Hertz, Philipp Lenard and others to discover the properties of cathode rays, culminating in J.J. Thomson's 1897 identification of cathode rays as negatively charged particles, which were later named electrons.

Deflection

Electrostatic deflection, a technique for modifying the path of charged particles by the use of an electric field

GRS 1915+105

Observations with high resolution radio telescopes such as VLA, MERLIN and VLBI show a bi-polar outflow of charged particles, which emit synchrotron radiation at radio frequencies.

Inverse-square law

The force of attraction or repulsion between two electrically charged particles, in addition to being directly proportional to the product of the electric charges, is inversely proportional to the square of the distance between them; this is known as Coulomb's law.

Jenny Harrison

The methods apply equally well to domains such as soap films, fractals, charged particles, and Whitney stratified spaces, placing them on the same footing as smooth submanifolds in the resulting calculus.

Laplace–Runge–Lenz vector

The hydrogen atom is a Kepler problem, since it comprises two charged particles interacting by Coulomb's law of electrostatics, another inverse square central force.

Magnetic trap

Penning trap, used to trap charged particles or ions in a combination of electrostatic potential and uniform magnetic field

Molecular Hamiltonian

The molecular Hamiltonian is a sum of several terms: its major terms are the kinetic energies of the electrons and the Coulomb (electrostatic) interactions between the two kinds of charged particles.

Nuclear electronics

Essential elements of such systems include fast detectors for charged particles, discriminators for separating them by energy, counters for counting the pulses produced by individual particles, fast logic circuits (including coincidence and veto gates), for identification of particular types of complex particle events, and pulse height analyzers (PHAs) for sorting and counting gamma rays or particle interactions by energy, for spectral analysis.

Vlasov equation

The Vlasov equation is a differential equation describing time evolution of the distribution function of plasma consisting of charged particles with long-range (for example, Coulomb) interaction.
