Production of a twin single hypernuclei and the Ξ- -nuclear interaction


Journal Article

An event accompanied by two single hyperfragments emitted from a Ξ- nuclear capture at rest was found in a nuclear emulsion. It is interpreted as a Ξ--12C bound system decaying into either a) Λ4H + Λ9Be, b) Λ4H + Λ9Be* or c) Λ4H* + Λ9Be. The binding energy of the Ξ-12C system is obtained as a) 3.70-0.19+0.18 MeV, b) 0.62-0.19+0.18 MeV and c) 2.66-0.19+0.18 MeV, respectively. The system is considered as a Ξ- hypernucleus in the cases a) and c). In case b), this event and another event of the same type (Yokohama event) can both be interpreted as a decay from the Ξ-12C system in 2P state when a shallow Ξ--nuclear potential is assumed. © 1995.
