Experimental data are presented on deuteron production in the target fragmentation region for 250 GeV/c π+ interactions with Al and Au nuclei, and compared with analogous data on proton production. Indications are observed for narrow structures in the (dπ-) effective mass system at ∼2.04 and ∼2.08 GeV.

We have measured the multiplicities of particles emitted in collisions between π's and p's of 1.5 to 2.5 GeV/c momentum with He and Ne nuclei in a streamer chamber. The chamber gas served as the target as well as the detecting medium. Because of the low density and 4π solid angle of the detector, it was possible to detect nuclear fragments with energies less than 5 MeV, and to essentially count all the particles emitted in a collision. Event distributions as a function of track multiplicity were obtained as well as correlated event distributions. NUCLEAR REACTIONS He (proton or pion, fragments and pions), Ne (proton or pion, fragments and pions), E=1.5, 2.0, 2.5 BeV/c; streamer chamber gas used as target with fragment energies as low as 5 MeV. Measured multiplicities and correlations of produced particle types.
