It is shown that the local thermodynamic description of the ground state of a many-electron system, earlier proposed by Ghosh, Berkowitz and Parr, is equivalent to a well defined approximation for the density matrix and therefore for the Wigner's distribution.

A formula is derived for the production rate of unstable particles that are produced in a thermalized region but whose decay products interact so weakly that they escape without thermalizing. The Bose-Einstein or Fermi-Dirac distribution is found to apply to unstable particles but modified by a Brei
