      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.

      Hyperfragments (HFs) produced in interactions of high energy pions and protons with emulsion nuclei have been investigated to deduce information on their mechanism of production. From these studies it is concluded that (a) long-range HFs (R⩾20µm.) which are due to fragments with mass number ≲15, are produced in the evaporation stage of the disintegrations of Ag and Br nuclei of emulsion, (b) short-range HFs (R⩽10µm.) are mainly due to residues of the target nuclei and a small fraction (≈10%) of them in the range 5<RHF⩽15µm. are due to fission type of processes that occur in high energy interactions and (c) the relative probability of sticking of Λ° to fragments withZ=2 to that with 3⩽Z⩽6 is roughly in the ratio 1:10.
