| electron velocity | <physics> The rate of motion of an electron. (05 Aug 1998) |
| electron-volt | <unit> A general unit of energy of moving particles, equal to the kinetic energy acquired by an electron losing one volt of potential, equal to 1.602 x 10-19 J. This is the energy an electron (or other particle of charge=1 such as a proton), gains as it is accelerated through a potential difference of 1 volt. In plasma physics the electron-volt is used as a unit of temperature when the mean particle energy is 1 eV, the temperature of the plasma is roughly 11, 600 Kelvin (the conversion from eV to K is via the Boltzmann constant). Abbreviation: eV (09 Oct 1997) |
| electron wavelength | <physics> The wavelength necessary to account for the deviation of electron rays in crystals by wave diffraction theory. It is numerically equal to the quotient of Planck's constant divided by the electron momentum, mv. = h / mv, where: h = Planck's constant m = mass of electron v = velocity of electron (05 Aug 1998) |
| emission electron | <physics>? A beta particle resulting from radioactive decay. (05 Mar 2000) |
| transition electron | An electron that moves from one energy level to another to fill a vacancy in a shell, with the emission of characteristic radiation. (05 Mar 2000) |
| transmission electron microscopy | <technique> Those forms of electron microscopy in which electrons are transmitted through the object to be imaged, suffering energy loss by diffraction and to a small extent by absorption. Acronym: TEM (18 Nov 1997) |
| free electron | <radiobiology> An electron not bound to an atom, molecule, or other particle via electromagnetic forces. (09 Oct 1997) |
