Study of hyperfragments. Part III. Multinucleon interactions of Λ° in hyperfragments

Abstract

1101 examples of non-mesic decay of hyperfragments, produced by high energy particles in nuclear emulsion stacks, have been used to obtain information on multinucleon interaction of Λ° hyperon in the decay of hyperfragments. From a study of events with two fast charged particles in decays of hyperfragments, the following two conclusions are drawn: (i) multinucleon interactions of Λ° in decay of hyperfragments is not significant; it occurs at the most in a few per cent of the cases, and (ii) there is strong evidence for the existence of final state interactions in decay of hyperfragments.
