Abstract
We discuss the possibility of production of a classical pion field in high energy nuclei-nuclei collisions. We show that the occupation numb er for the produced pions can be large as required for the case of a c lassical field. By examination of the cooling we conclude that in the ''quench'' scenario it is unlikely to produce a large domain of DCC. T he size of domain can be essentially larger due to the temperature dep endence of the parameters of the effective Lagrangian. However even in this case the decay of the DCC leads to the production of no more tha n several tenths of pions which are not easy to distinguish from the ' 'normal'' pions.
