Fermi: exclusion-based statistics of an ideal gas

Contribution grade

Quantum statistical mechanics · Quantum statistical mechanics

Reference score190,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

An at-most-one occupation hypothesis is extended to ideal-gas state counting and thermodynamics, yielding a degeneracy distribution and low-temperature pressure/heat-capacity consequences.

Scientific scope

An at-most-one occupation hypothesis is extended to ideal-gas state counting and thermodynamics, yielding a degeneracy distribution and low-temperature pressure/heat-capacity consequences. The 1926 note states principles and results, reserving mathematical details for a later work. It assumes an ideal gas and the exclusion hypothesis; it is not an experimental validation or a model of every interacting gas. The inspected English translation dates from 1999.

Evidence

Source-linked, scoped account of the original work. The published scope states the scientific assumptions and remaining verification limits. WRS has not independently certified the full proof, experimental result or system benchmark.
