Double differential and total cross sections of the ({pi}{sup {minus}},{ital pd}), ({pi}{sup {minus}},{ital dp}), and ({pi}{sup {minus}},{ital dd}) reactions on {sup 12}C were measured over a wide angular range at an incident pion kinetic energy of 165 MeV. The shape of the angular distributions of the differential cross sections of these reactions is in most cases similar to that of the {sup 12}C({pi}{sup {minus}},{ital pp}){ital X} reaction. These similarities seem to indicate a pickup mechanism in certain regions of phase space following three-nucleon absorption. Contributions from both three-nucleon absorption and two-step processes are found to be important for the above type of reactions.
