The production of neutral pions has been studied in the O-16 + Al-27, Ni-58, Pb-208 reactions at 95 MeV/nucleon. Inclusive pion differential distributions d-sigma/dp(t), d-sigma/dT(pi), and d-sigma/d-OMEGA have been measured by detecting the two-pion decay gamma-rays in a setup of 8 lead glass Cherenkov detector telescopes.

Abstract
The production of neutral pions has been studied in the O-16 + Al-27, Ni-58, Pb-208 reactions at 95 MeV/nucleon. Inclusive pion differential distributions d-sigma/dp(t), d-sigma/dT(pi), and d-sigma/d-OMEGA have been measured by detecting the two-pion decay gamma-rays in a setup of 8 lead glass Cherenkov detector telescopes. The data are discussed in the framework of a moving thermal source model. It is shown that the shape of the pion energy spectra is better described if mean field effects on the primary pion-production cross section and pion reabsorption are included in the calculation.File in questo prodotto:
