Inclusive spectra have been measured for deuterons and tritons knocked out of the nuclei /sup 6/Li, /sup 7/Li, /sup 12/C, /sup 32/S, /sup 63/Cu, /sup 115/In, and /sup 209/Bi at angles 0/sup 0/ by negative pions with momentum 740 MeV/c. Two important differences are indicated between (..pi..,d) and (p,d) reactions. First, in all nuclei there is no quasielastic ..pi.. backscattering peak in the measured momentum spectra of deuterons. Second, the A-dependence obtained for the (..pi..,d) cross section is poorly described by a power function and can be only roughly approximated by a dependence sigmaapprox.A/sup 2//sup ///sup 3/, whereas for the (p,d) reaction sigmaapprox.A/sup 1//sup ///sup 3/ satisfactorily describes the experimental data. The two facts indicate a difference in the mechanisms of deuteron knockout from nuclei by pions and by protons. An attempt is made to explain the experimental results by taking into account two-fold interactions in the nucleus.
