Résumé :

A systematic search has been made for decays of A0-hyperons around 5262 interactions of K--mesons at rest in photographic emulsion. From the 41 decays of correlated A0-hyperons observed in this sample, it has been estimated that (47±7)% of all K--meson interactions at rest in emulsion nuclei emit neutral hyperons. On consideration of the conservation of strangeness it is suggested that cryptofragments are formed in (30±7)% of all such K--meson absorptions and that the non-mesonic decays of these cryptofragments give rise to a considerable proportion of the protons of energies greater than 60 MeV emitted from K--meson captures. © 1961 Società Italiana di Fisica.
