Binding energies of the Λ0-hyperon in hypernuclei

摘要: Abstract An analysis of 29 hypernuclei produced by the interactions K - -mesons and Σ -hyperons in nuclear emulsion decaying π -mesic mode, is presented. Binding energies Λ 0 -hyperon H 4 (6 events), He (4 5 (9 events) ΛLi 9 (1 event) are obtained as (2.37±0.30) MeV, (2.27±0.27) (3.27 ± 0.18) MeV (7.75±0.80) respectively. The binding derived from Q value determined same stack which hyperfragment data also originated. This makes systematic errors negligible; quoted therefore only statistical. Besides most commonly occuring decay mode , rare → 3 +H 2 + has been observed.
