### Bose-Einstein Statistics

**(B-E Statistics, Bose-Einstein Distribution)**
(possible distribution of particles not bound by Pauli exclusion)

**Bose-Einstein Statistics**
(**B-E Statistics** or the **Bose-Einstein Distribution**)
describes a distribution of the energy levels of non-interacting,
indistinguishable Particles if they are in Thermodynamic Equilibrium
and are **Bosons**, i.e., not bound by the Pauli Exclusion Principle.

The Pauli Exclusion Principle, which applies to some other types of
particles (called **Fermions**), is the fact
that no more than one such particle within a Quantum
system will ever occupy the same quantum state.
The analogous distribution of their energy
levels is called **Fermi-Dirac Statistics**
or **Fermi-Dirac Distribution**.

**Bosons** include Photons and gluons and **Fermions**
include quarks, protons, and neutrons,
but a composite particle with an even number of
fermions (e.g., a Helium nucleus of Isotope 4) is a boson,
and helium's **Superfluid** state at sufficiently low temperatures
is a result of B-E statistics.

If the Temperature is sufficiently high and/or
the particles are at a sufficiently low concentration,
both Bose-Einsteins statistics and Fermi-Dirac statistics
approach the classical formulation, **Maxwell-Boltzmann Statistics**.
