Delayed clusters accompanying nonmesonic weak decay of the $Λ$-hypernuclei: a clue to nonleptonic processes

The nonmesonic decay of $Λ$-hypernuclei provides access to the nonleptonic weak decay process $ΛN \to NN$, which is achievable only through the observation of hypernuclear ground-state decays. We continue the discussion of some specific cases which make it possible to detect a few exclusive transitions, namely, the stripping of nucleon from the ground state results in a resonance state decaying via emission of two clusters. Delayed clusters accompanying weak decay of light hypernuclei give a unique information on spin dependence of the weak decay matrix elements.
