Electrons and how
Electrons and how they interact with electromagnetic fields are important in our understanding of chemistry and physics.
In 1936, the two published a paper, " The Passage of Fast Electrons and the Theory of Cosmic Showers " in the Proceedings of the Royal Society, Series A, in which they used their theory to describe how primary cosmic rays from outer space interact with the upper atmosphere to produce particles observed at the ground level.
Electrons and they
Electrons are the charge carriers in metals and they follow an erratic path, bouncing from atom to atom, but generally drifting in the opposite direction of the electric field.
Electrons are responsible for emission of most EMR because they have low mass, and therefore are easily accelerated by a variety of mechanisms.
Electrons are particulate radiation and, hence, have cross section many times larger than photons, so that they do not penetrate the product beyond a few inches, depending on product density.
Electrons can absorb energy from photons when irradiated, but they usually follow an " all or nothing " principle.
Electrons in the emitters, or the " holes " in the collectors, would cluster at the surface of the crystal where they could find their opposite charge " floating around " in the air ( or water ).
Electrons will move to the left side ( uncovering positive ions on the right side ) until they cancel the field inside the metal.
Electrons exiting the source cavity are velocity modulated by the electric field as they travel through the drift tube and emerge at the destination chamber in bunches, delivering power to the oscillation in the cavity.
* Electrons are fermions, but when they pair up into Cooper pairs they act as bosons, and so can collectively form a coherent state at low temperatures.
Electrons inside these long focus coils take helical paths as they travel along the length of the tube.
Electrons in non-bonding orbitals tend to be in deep orbitals ( nearly atomic orbitals ) associated almost entirely with one nucleus or the other, and thus they spend equal time between and not between nuclei.
Electrons which are trapped in an electromagnetic cavity are in a bound state and thus organise themselves as they do in a regular atom, thus expressing chemical-like behaviour.
Electrons, within an electron shell around an atom, tend to distribute themselves as far apart from each other, within the given shell, as they can ( due to each one being negatively charged ).
Electrons do not penetrate as deeply into matter as X-rays, hence electron diffraction reveals structure near the surface ; neutrons do penetrate easily and have an advantage that they possess an intrinsic magnetic moment that causes them to interact differently with atoms having different alignments of their magnetic moments.
Electrons were ideal for the role, as they are abundant and easily accelerated to high energies due to their electric charge.
Electrons and interact
Electrons from ionized atoms interact mainly with neutral atoms, causing thermal bremsstrahlung radiation.
Electrons can be used in these situations, whereas X-rays cannot, because electrons interact more strongly with atoms than X-rays do.
Electrons and with
These he interpreted as " negative-energy electrons " and attempted to identify them with protons in his 1930 paper A Theory of Electrons and Protons However, these " negative-energy electrons " turned out to be positrons, and not protons.
Electrons which diffuse from the cathode into the P-doped layer, or anode, become what is termed " minority carriers " and tend to recombine there with the majority carriers, which are holes, on a timescale characteristic of the material which is the p-type minority carrier lifetime.
Electrons are fermions with S = 1 / 2 ; quanta of light are bosons with S = 1.
For instance, " Electrons attract protons " and " Electrons have negative charge " employ the terms " protons " and " negative charge " ( with the latter also implicitly using the concept of " charge ").
Electrons can be exchanged between materials on contact ; materials with weakly bound electrons tend to lose them, while materials with sparsely filled outer shells tend to gain them.
Electrons in this system are not conserved, but are rather continually entering from oxidized 2H < sub > 2 </ sub > O ( O < sub > 2 </ sub > + 4 H < sup >+</ sup > + 4 e < sup >-</ sup >) and exiting with NADP < sup >+</ sup > when it is finally reduced to NADPH.
* Bhees: Beams of High Energy Electrons, these are beams of focused and accelerated electrons with considerable penetrating power.
Electrons ( and positive charge carriers ) come with their own built-in negative feedback.
This project was continued with the launch of From Electrons to Elections, a science and technology policy guide to the 2008 elections.
From Electrons to Elections is a non-partisan resource designed to educate young voters on science, technology, and health issues and provide them with the platforms of the leading political candidates on these subjects.
Electrons can only reach ( and " illuminate ") a given plate element if both the grid and the plate are at a positive potential with respect to the cathode.
Electrons are delocalized along the conjugated backbones of conducting polymers, usually through overlap of π-orbitals, resulting in an extended π-system with a filled valence band.
Electrons from the cathode collide with the anode material, usually tungsten, molybdenum or copper, and accelerate other electrons, ions and nuclei within the anode material.
* Gover, " Collective and Single Electron Interactions of Electron Beams with Electromagnetic Waves and Free Electrons Lasers ".

Electrons and electromagnetic
Electrons are bound by electromagnetic wave mechanics into orbitals around atomic nuclei to form atoms, which are the building blocks of molecules.
Electrons in atoms and molecules can change ( make transitions in ) energy levels by emitting or absorbing a photon ( of electromagnetic radiation ) whose energy must be exactly equal to the energy difference between the two levels.
Electrons appear as a track in the inner detector and deposit all their energy in the electromagnetic calorimeter.
Electrons and fields
Electrons and ions in the magnetosphere, for example, will bounce back and forth between the stronger fields at the poles.
Electrons and are
Electrons that are bound to atoms possess a set of stable energy levels, or orbitals, and can undergo transitions between them by absorbing or emitting photons that match the energy differences between the levels.
Electrons that populate a shell are said to be in a bound state.
Electrons in an s orbital benefit from closer proximity to the positively charged atom nucleus, and are therefore lower in energy.
Electrons ( the other major component of the atom ) are leptons.
* Electrons are also transferred to the electron acceptor Q, forming QH < sub > 2 </ sub >.
Electrons are extracted from metal electrodes either by heating the electrode, causing thermionic emission, or by applying a strong electric field and causing field electron emission.
Electrons are at the heart of cathode ray tubes, which have been used extensively as display devices in laboratory instruments, computer monitors and television sets.
