Abstract
The total cross section for pion production in the reaction pd→pd has been measured for bombarding energies from =208.4 MeV to 294.6 MeV. This corresponds to maximum pion momenta η=/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 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 pn→d elementary process.
