Abstract
We present data on pi0 emission coincident with projectile-like fragme nts from Ar-36 + Au-197 and Ar-36 + C-12 reactions at 95 MeV/u. The pi on polar and azimuthal distributions, obtained for different impact pa rameters, are interpreted in terms of strong final-state interactions. We propose to exploit pion shadowing as a probe of the competition be tween attractive and repulsive forces in nucleus-nucleus collisions.
