单词 boson
释义
boson

Physics
  • An elementary particle (or bound state of an elementary particle, e.g. an atomic nucleus or an atom) with integral spin; i.e. a particle that conforms to Bose–Einstein statistics (see quantum statistics), from which it derives its name. Compare fermion.


Astronomy
  • A particle such as a photon, a meson, an atomic nucleus of even mass number (e.g. the commonest type of helium nucleus), or the hypothetical graviton which has a zero or integer value of spin. They do not obey the Pauli exclusion principle. Bosons are named after the Indian physicist Satyendra Nath Bose (1894–1974). See also Fermion.


Chemistry
  • A particle or system that obeys Bose–Einstein statistics (see quantum statistics). Combining quantum mechanics with special relativity theory gives a result that a boson has to have an integer spin. A photon is an example of a boson.
