UNDERSTANDING OF THE FREEZE-OUT IN ULTRA-RELATIVISTIC HEAVY-ION COLLISIONSBoris Tomášik Niels Bohr Institute, Blegdamsvej 17, DK-2100 Copenhagen, Denmark I discuss the quantities and effects important for the freeze-out and outline a formalism for the description of continuous decoupling of particles from the fireball. Then, I present a calculation of the scattering rates of pions at various temperatures and argue that it is important to take continuous particle decoupling into account when modelling the collision dynamics.
