| Résumé : | The transformation theory developed by Prigogine and coworkers provides a new description of the dynamics in terms of dressed particles (the "physical" particles). In this paper, we are interested in the properties of the dressed particles in the case of a moderately dense quantum gas obeying Boltzmann statistics. We calculate, to the first order in the density, the energy of the physical particles and the singlet equilibrium distribution function. The results provide a generalization of the classical mechanical results obtained in a previous paper by Allen and Nicolis. © 1971. |
