  The (pi+,pd), and (pi+,dd) reactions were investigated with pions of 100 and
165 MeV kinetic energy on 6Li and 12C targets. In comparison with previously
published (pi+,pp) data on the same targets and at the same beam energies,
kinematic regions were identified in which the neutron pickup process n+p->d
dominated the observed deuteron yield. The importance of this mechanism
increases with energy, contributing half of the observed cross section at 165
MeV. The contribution of direct quasi-triton absorption is significant only at
100 MeV.
