摘要：

Neutral pion production has been studied in the Ar-36 + Al-27 reaction at 95 MeV/nucleon with the aim to get a quantitative estimate of its impact-parameter dependence. A near 4pi multidetector has been used to detect both the gamma rays originating from the pi0 decay and the associated charged particles. The charged particle multiplicity has been used in the present analysis as a global variable to extract the impact parameter scale. A comparison with a Boltzmann-Nordheim-Vlasov calculation, which takes into account the effect of pion reabsorption in the nuclear medium, has been performed.
