TL;DR: In this paper, a study of particle interactions in emulsion stacks exposed to 1.3 and 1.5 Bev/c K/sup -/ meson beams gives support to the idea that hyperfragments of range less than 10 mu m are residual spallation products containing trapped LAMBDA / sup o/ hyperons resulting from K/Sup -/ interactions in the emulsion nuclei.

TL;DR: In this article, a double hyperfragment was found to have been formed by XI capture on carbon, and the ranges and angles involved in these and subsequent decay processes were given.
