Abstract

The widths of the conversion processes → ΛN, ΞN → ΛΛ in nuclear mattter were calculated based on the model of single-boson exchange. It was established that the conversion width for Σ is significantly reduced by the interference of the contributions of separate mesons to the conversion amplitude. The conversion width obtained for Ξ in nuclear matter turned out to be less than 1 MeV.
