(redirected from Mass of electron)Also found in: Thesaurus, Medical, Encyclopedia. e·lec·tron (ĭ-lĕk′trŏn′) n. Abbr. e A stable elementary particle in the lepton class having a negative electric charge of 1 elementary unit (about 1.602 × 10-19 coulombs) and a mass of ...
This may appear problematic with the theory of special relativity. For an electron transiting between the maximum of the valence band and the minimum of the conduction band, or vice versa, the conservation of momentum, however, cannot be fulfilled with the absorption or emission of a photon ...

lower limit on the mass of the scalar electron, as extracted from the single photon experiments, is affected by the way the background from radiative neutrino pair production is handled. We argue that some of the results presented at the Berkeley conference are overoptimistic, and that the ...
A variety of ion interactions have been studied for the purpose of ion dissociation and ion transformation, including ion/neutral, ion/photon, ion/electron, and ion/ion interactions. A wide range of phenomena have been observed, many of which have been explored/developed as means for structural...
The microcausality condition allowing to express amplitudes Tsub(i)(ν, q) of the virtual photon forward scattering by a hadron in terms of the Wsub(i)(ν, q) functions for the electroproduction process, is applied to explain the mass differences between particles forming the isotopic multiple...

How does the mass of a nucleon differ with the mass of an electron? Atom and Subatomic Particles An atom is considered as the smallest particle of a chemical element that is existing in nature. All substances are made up of either neutral atoms or ionized atoms. The atoms of al...
