;
Results are given from an investigation of a stack of 600 mu m Ilford G- 5 emulsions, exposed to 4.5-Bev pi /sup -/ mesons. The nature, emission spectra, and angular distributions of unstable nuclear fragments and hyperfragments produced in the emulsions were studied. The ejected fragments selected for characterization studies were Li/sup 8/ Li/sup 9/ Be/sup 8/ B/sup 8/ , B/sup 12/, and C/sup 12/. The modes of decay and excited levels are outlined for these fragments. Data on 29 hyperfragrnents identified with certainty are reported. Their angular and energy distribution does not support the view that their mechanism of production is substantially different from that of unstable fragments of nonhyperonic origin. (B.O.G.)
