The cross sections for the [ital p]([ital e],[ital e][prime][pi][sup +])[ital n] and [ital d]([ital e],[ital e][prime][pi][sup +])2[ital n] reactions are calculated using a simple model with pion, nucleon and [Delta]-resonance degrees of freedom, for the kinematical conditions used in a recent Saclay experiment. The final-state interactions between the two outgoing neutrons are found to have a large effect on the [ital d]([ital e],[ital e][prime][pi][sup +])2[ital n] reaction. The calculated quenching of the [pi][sup +] production cross section for deuterium is in agreement with that observed experimentally. It is predicted that, due to the strong final-state interaction in the singlet [ital S] state of the two neutrons, the [ital e],[ital e][prime][pi][sup +] cross-section can have a large dependence on the orientation of deuteron spin. In principle this dependence can be observed with tensor polarized deuterium targets under suitable kinematical conditions.
