Observables for the pd→3Hπ+ and pd→3Heπ0 reactions in a pp→dπ+ model

Differential cross sections and spin observables Ay, iT11, T20, and T22 are calculated for the pd→3Hπ+ reaction in a pp→dπ+ model at energies near threshold. The results are compared with experimental data for the reactions pd→Heπ0 and dp→3Heπ0. Good agreement of these predictions with the data for the proton analyzing powers is obtained, and for most of the other observables satisfactory agreement is found. Effects of various assumptions in the model are investigated and discussed.
