I discuss the effects and quantities that influence the decoupling of particles from the fireball. The crucial role is played by the scattering rate. I show the results for the scattering rate at SPS and RHIC and discuss their implications. Strongly interacting matter is produced in ultra-relativistic collisions of heavy atomic nuclei at SPS and RHIC. The system cools down quickly, however, and hadronic spectra are formed as soon as when interactions disappear. Hence, they carry no direct… CONTINUE READING
