rate -.pa, below by which are distinctly manifested the
quantum properties of perfect gas, caused by the identity of the
particles (see identities principle), i.e. gas becomes degenerate. For the Bose gas from the particles with the
nontrivial mass of v. T. it is defined as rate -.pa, lower than which
occurs Base- Einstein condensation - passage of a some fraction of the particles of the system
into the state with the zero pulse. For the
farm- gas v. T. it is equal to max, energy of
particles with abs. zero, expressed in the degrees (i.e. divided into Boltzmann constant); with v. T.
almost all lowest energ. levels of Fermi's gas prove to be filled.
