This quantity, overlooked until now, is computed and it is shown how it could play a role for this system. Other possible applications are also mentioned.4 pages, LaTeX, to appear in Proceedings of the 5th International Workshop on Thermal Field Theories and Their Applications, August 1998, Regensburg, GermanyHigh Energy Physics - TheoryHigh Energy Physics - Phenomenologytext
