▪ I. boson Nuclear Physics.|ˈbəʊzɒn|
[f. the name of the Indian physicist S. N. Bose (1894–1974) + -on.]
Any particle which has a symmetric wave-function and which therefore obeys Bose-Einstein statistics; also attrib. Cf. fermion. Also intermediate boson, a boson postulated to exist as a quantum or intermediary of weak interactions.
1947P. A. M. Dirac Princ. Quantum Mech. (ed. 3) ix. 210 The new statistics was first studied by Bose, so we shall call particles for which only symmetrical states occur in nature bosons. 1953M. Schönburg in Nuovo Cimento X. 429 When the coordinates and momenta are given at the time t = o, we must take for bosons (28a)..and for fermions (28b). 1955W. Pauli N. Bohr 33 The coupling between one Boson field and one Dirac field. 1955D. ter Haar in Rev. Mod. Physics XXVII. 312/2 Fermi-Dirac particles. Such particles are sometimes called fermions and the Bose-Einstein particles, bosons. 1958Physical Rev. CX. 1482/2 The existence of such a heavy boson..will itself lead to the occurrence of decays which are not found in nature, and which would not occur in any detectable amount if there are no intermediate bosons. 1961Powell & Crasemann Quantum Mech. xii. 453 Particles whose spin is an integral multiple of ℏ are bosons. 1965New Statesman 17 Sept. 393/3 One of these tracks may well be the first sign of the existence of the long-sought particle of matter called intermediate boson.
