Abstract
In an emulsion-counter hybrid experiment performed at J-PARC, a absorption event was observed which decayed into twin single- hypernuclei. Kinematic calculations enabled a unique identification of the reaction process as NBe + He. For the binding energy of the hyperon in the -N system a value of MeV was deduced. The energy level of is likely a nuclear state which indicates a weak - coupling.
