Observation and Analysis of K − Interactions

摘要: In nuclear emulsions, 289 ${K}^{\ensuremath{-}}$ mesons were observed. The mass and lifetime of is the same as that ${K}^{+}$ mesons. mean free path in emulsion geometric. Charge-exchange scattering inelastic ${K}^{\ensuremath{-}}$-nucleus are rare. Positive hyperons emitted 8% capture stars, negative about 9%, hyperfragments 5%. It estimated a ${\ensuremath{\Lambda}}^{0}$ trapped without production visible hyperfragment an additional 8%. A captured by one nucleon with formation $\ensuremath{\Sigma}$ hyperon pion 0.77 cases, creation approximately 0.18 events. Capture two nucleons occurs roughly 0.05 cases. From comparison emission frequencies it concluded attractive potential for must be less than 20 Mev. Limits paths ordinary scattering, charge-exchange absorption matter given. trapping nuclei discussed.
