ALL meanings of fermion
fer·mi·on
F f - noun fermion A subatomic particle, such as a nucleon, that has half-integral spin and follows the statistical description given by Fermi and Dirac. 1
- noun fermion any particle that obeys the exclusion principle and Fermi-Dirac statistics; fermions have spins that are half an odd integer: 1/2, 3/2, 5/2, …. 1
- noun fermion A particle with totally antisymmetric composite quantum states, which means it must obey the Pauli exclusion principle and hence Fermi–Dirac statistics. They have half-integer spin. Among them are many elementary particles, most derived from quarks. Compare boson. 0
- noun fermion any of a group of elementary particles, such as a nucleon, that has half-integral spin and obeys Fermi-Dirac statistics 0
- noun fermion any of a class of subatomic particles that obey the Pauli exclusion principle and have fractional spin, including the leptons, quarks, and baryons 0
