TL;DR: In this paper, a coincidence measurement of two nucleons emitted from the nonmesonic weak decay (NMWD) of Li and Kipf formed via the Li-pi+K^+) reaction was performed, and the energies of the nucleons and the pair number distributions in the opening angle between them were measured.

TL;DR: In this article, high-resolution γ spectroscopy of hypernuclei using Hyperball has revealed detailed level structure of several p-shell Λ-spin-dependent interactions and allowed us to extract the strengths of ΛN spin-dependent interaction.

TL;DR: In this article, a new channel of NMWD, namely the recently confirmed three-body channel, seems to have a surprisingly big branching ratio so that it makes its accurate measurement prerequisite of the baryon-baryon weak interaction study.

TL;DR: In this article, the discrepancy of asymmetry parameter between experimental and theoretical values has been solved and the I = 1/2 rule for ΔS = 1 decay would hold or not in NMWD.

TL;DR: The first measurement of the branching ratio of the three-body NMWD process and the renormalized intra-nuclear cascade method adopted to disentangle the contribution of the 3-body process out of those due to final state interaction were discussed in this article.
