strangeness systems such as double-Λ hypernuclei and H-dibaryons. More than 10% of Ξ−
hyperons produced in the (K−, K+) reaction were brought to rest in the nuclear emulsion. We
have obtained 98 candidate events of nuclear capture at rest of Ξ− hyperons which are
described in this report. Among those, four events were identified as sequential weak decay
of double-Λ hypernuclei. The binding energies of Ξ−-(12C, 14N and 16O) states have been …
