Abstract
The production of neutral pions in nucleus nucleus collisions with 44 MeV/u Ar projectiles from the accelerator GANIL has been observed. The angular distributions indicate a collective production process, and the pion spectra reflect properties of the collision dynamics.

Additional information
The measurement of the rather low cross sections in this experiment was only possible through the intensive support by the engineers and technicians at GANIL which we gratefully acknowledge.
