Neutral pion production in the ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$${+}^{27}$Al reaction at 94 MeV/nucleon

The production of neutral pions in the reaction ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$${+}^{27}$Al at 94 MeV/nucleon was studied with a multidetector, which includes 180 ${\mathrm{BaF}}_2$ modules. Kinetic energy spectra for several laboratory angles were measured. The total cross section for neutral pion production was deduced. Results were compared with previous findings on charged pions from the same reaction at the same energy and with the prediction of a dynamical model based on the numerical solution of the Boltzmann-Nordheim-Vlasov equation.
