On the emission of fast∑-hyperons from disintegrations due to the capture ofK--mesons by light nuclei

Abstract
A study has been made of those disintegrations produced in photographic emulsion by the nuclear capture at rest of K--mesons, from which fast charged ∑-hyperons are emitted. In a sample of 63 events, six were analyzed unambiguously as being due to absorption in carbon, nitrogen or oxygen without the emission of any neutrons. An additional eight were found to be consistent with capture by a light nucleus with the emission of one neutron only in each case. The fraction of disintegrations due to K--meson capture in light nuclei from which a fast charged ∑-hyperon is emitted has been estimated.
