The total cross section for pion production in the reaction [ital pd][r arrow][ital pd][pi][sup 0] has been measured for bombarding energies from [ital T][sub [ital p]]=208.4 MeV to 294.6 MeV. This corresponds to maximum pion momenta [eta]=[ital p][sub [pi],c.m.]/[ital m][sub [pi]][ital c] between 0.099 and 0.96. The experiment was performed using an electron-cooled proton beam and an internal deuterium gas jet target. The resulting [sigma][sub tot] changes by almost four orders of magnitude over the covered energy range. The results are compared to a model which assumes quasi-free production via the [ital pn][r arrow][ital d][pi][sup 0] elementary process.
