Query: Delta-33 medium mass modification and pion spectra   We study the pi+- spectra obtained in 2,4,6,8 A GeV Au-Au collisions within
the thermal model. We find that the main features of the data can be well
described after we include the pions from the decay of the Delta-resonance with
medium mass modification.
