Abstract
We obtain a uniformly valid leading-order approximation for the two-body correlation function of a gas which is not in thermodynamic equilibrium. We demonstrate that the correlation length is finite, of the order of the mean-free path, even without the inclusion of three-body collisions. The new result, which is in sharp contrast to previous calculations, is obtained by correcting an inconsistency in Bogoliubov's expansion method.Keywords
