half-integer
Noun
Meaning
half-integer (plural half-integers)
(mathematics) Any number obtained by dividing an odd integer by two
Examples
"Half-integer spin" means that the intrinsic angular momentum value of fermions is (reduced Planck's constant ) times a half-integer (1/2, 3/2, 5/2, etc.).
Overview The Pauli exclusion principle dictates the behavior of all fermions (particles with "half-integer spin "), while bosons (particles with "integer spin") are subject to other principles.
The bosonic behavior of some of these alkaline gases appears odd at first sight, because their nuclei have half-integer total spin.
It can also be found in Fermi–Dirac statistics (for particles of half-integer spin ) and Bose–Einstein statistics (for particles of integer spin).
It states that bosons have integer spin, and fermions have half-integer spin.
Particles of half-integer spin exhibit Fermi–Dirac statistics and are fermions.
