摘要：

In high energy heavy ion collisions the pion multiplicity is large, and one might expect that pions are radiated semi-classically. The axial symmetry of the collision and approximately zero isotopic spin of the colliding nuclei result then in peculiar isotopic spin-azimuth correlations of the produced pions. These correlations can be tested by analyzing the double differential cross section for charged or neutral pion production.
