Abstract
In this work the nuclear captures of Σ- hyperons have been studied by analogy with the analysis of K- meson captures produced on the light and heavy emulsion nuclei. A stack of Ilford K-3 nuclear emulsions was exposed to a beam of slowed K- mesons at the CERN proton·synchrotron. Of all the possible reactions that occurred in this detector, only the interactions of Σ- hyperon and K- meson with a bound proton from a complex nucleus of the emulsion were selected. The experimental measurements have shown, with restricted detection possibilities, that the Σ- hyperon capture stars are produced with a frequency of (58.0 ± 2.6) % on heavy and with (42.0 ± 1.9) % on light nuclei.
