Description

The free paths of nucleon and pion quasi particles in heated dense nuclear matter are calculated taking into account the total NN-interaction amplitude. The softening of the pionic degree of freedom with density essentially manifests itself in decrease of free paths of particles. The obtained results support the applicability of the expanding fireball model to description of nucleus-nucleus collisions
