Mass in special relativity — incorporates the general understandings from the concept of mass energy equivalence. Added to this concept is an additional complication resulting from the fact that mass is defined in two different ways in special relativity: one way defines… … Wikipedia
Electron cyclotron resonance — is a phenomenon observed both in plasma physics and condensed matter physics. An electron in a static and uniform magnetic field will move in a circle due to the Lorentz force. The circular motion may be superimposed with a uniform axial motion,… … Wikipedia
Electron diffraction — is a technique used to study matter by firing electrons at a sample and observing the resulting interference pattern. This phenomenon occurs due to the wave particle duality, which states that a particle of matter (in this case the incident… … Wikipedia
Electron — For other uses, see Electron (disambiguation). Electron Experiments with a Crookes tube first demonstrated the particle nature of electrons. In this illustration, the profile of the cross shaped target is projected against the tube face at right… … Wikipedia
electron tube — an electronic device that consists, typically, of a sealed glass bulb containing two or more electrodes: used to generate, amplify, and rectify electric oscillations and alternating currents. Also called electronic tube. Cf. gas tube, vacuum tube … Universalium
electron — /i lek tron/, n. 1. Also called negatron. Physics, Chem. an elementary particle that is a fundamental constituent of matter, having a negative charge of 1.602 × 10 19 coulombs, a mass of 9.108 × 10 31 kilograms, and spin of 1/2, and existing… … Universalium
electron — (me) the mass of the electron, often used as a unit of mass in particle physics. An electron has a mass of about 9.109 382 x 10 31 kilogram, 9.109 382 x 10 28 gram, or 0.510 9989 million electronvolts (MeV, see next two entries) … Dictionary of units of measurement
Mass spectrometry — (MS) is an analytical technique that measures the mass to charge ratio of charged particles.[1] It is used for determining masses of particles, for determining the elemental composition of a sample or molecule, and for elucidating the chemical… … Wikipedia
Mass spectrum — Electron ionization mass spectrum of toluene [4]. Note parent peak corresponding to molecular mass M = 92 (C7H8+) and highest peak at M 1 = 91 (C7H7+, quasi stable tropylium cation). A mass spectrum is an inten … Wikipedia
Mass excess — The mass excess of a nuclide is the difference between its actual mass and its mass number in atomic mass units.[1] It is one of the predominant methods for tabulating nuclear mass. The mass of an atomic nucleus is well approximated by its mass… … Wikipedia
