Abstract

• The main aim of this research paper is to determine the type of hypernucleus from a single lambda hypernucleus event, which is an event accompanied by one single Λ hyperfragment and invisible Λ hyperon emitted from a Ξnuclear captured at rest, was found in nuclear emulsion of KEK- E373 experiment . It is interpreted as Ξ- - 14N system decaying into and hyperfragment decay into . The type of hypernucleus can be determined as lambda boron 12 hypernucleus .
