; ;
The reactions (..pi../sup +/ ,..pi../sup +/ /ital d/) and (..pi../sup /minus// ,..pi../sup /minus///ital d/) in Ag and Br nuclei have been investigated in nuclear emulsions at a pionenergy 170 MeV. Integrated cross sections have been determined, and data havebeen obtained for energy and angular spectra of deuterons, momentum and angulardistributions of recoil nuclei, and differential cross sections for scatteringof mesons. A comparison with a calculation in the pole approximation is made forthe diagram with a virtual deuteron. The dependence of the contribution ofdirect deuteron knockout on the sign of the initiating mesons is determined.Indications are obtained of a substantial admixture of the nucleon-pickupmechanism in the investigated reactions.
