  The transverse mass spectra of light mesons produced in Au-Au collisions at
200 GeV/nucleon are analyzed in Tsallis statistics. In high energy collisions,
it has been found that the spectra follow a generalized scaling law. We applied
Tsallis statistics to the description of different particles using the scaling
properties. The calculated results are in agreement with experimental data of
PHENIX Collaboration. And, the temperature of emission sources is extracted
consistently.
