A category of particles that have "odd-half-integer" spins (/; /; ...) and obey the Pauli Exclusion Principle. Examples include electrons, electron neutrinos, and quarks. See also: spin, Pauli Exclusion Principle, electron, quark, neutrino, boson, Debriefing
Particles with half-integer spin
Particles of half-integer spin that compose matter, comprising quarks and leptons.
Particles which obey Fermi-Dirac statistics.
All known particles are either fermions or bosons. Fermions have half-integral quantum numbers of spin: 1/2, 3/2, etc. They obey the Pauli exclusion principle in that no two fermions can occupy the same quantum state. Examples of fermions are the electron, proton, neutron, and quark.
A particle with the angular spin momentum of (n+.5)h where n={0,1,2,...}. Examples are quarks and electrons.
Class of elementary particlesthat includes the electrons, neutrinos, nucleons, and other baryons. Identical fermions obey Pauli's exclusion principle and follow the Fermi-Dirac distribution at thermal equilibrium.
Elementary particles such as electrons, quarks, neutrinos, protons and neutrons are fermions
