A non-mesonic decay of a11ΛB hyperfragment

Abstract

An event is described which is interpreted as the non-mesonic decay of ¹¹ _Λ B into ⁸Li, a deuteron and a proton. Any other interpretation is seen to have a negligible probability of being correct. The binding energy of the Λ °-hyperon in the ¹¹ _Λ B hypernucleus is found to be11.3±0.8 Mev.
