摘要：

We calculate the isospin symmetry violating effects to the reactions pp --> d pi(+) and np --> d pi(0) arising from the different hadron masses and from the Coulomb interaction between the positive pion and the deuteron. These effects are large enough in the cross section and analyzing power A(gamma) that they should be taken into account in comparisons of accurate experiments in different charge channels.
