Abstract
We consider the thermodynamic potential of an component Fermi gas with a short-range interaction obeying symmetry. We analyze especially the nonanalytic part of in the temperature at low . We examine the temperature range where one can observe this contribution and discuss how it can be extracted experimentally.
