Hyperfragment production and decay and the non-mesic absorption rate for stopping K− mesons in neon

In a bubble chamber study of stopping K − neon interactions, we have measured the hyperfragment production probability (trapped Λ events) following K − absorption to be 9.5 ± 3%. The mesic decay probability for these hyperfragments was less than 9% and the multi-nucleon or non-mesic K − absorption probability was 22 ± 4%.
