The in-medium mass modification of nucleons and it's impact on the freeze out process is studied. A considerable modification of the thermodynamical parameters temperature, flow-velocity, energy density and particle density has been found in comparison with evaluations which use a constant vacuum nucleon mass.6 pages, 4 figures, Proceeding of the Conference "Quark Matter 2005", 4th - 9th August 2005, Budapest/HungaryNuclear Theorytext
