✦ Synopsis

The weak nonmesonic decay of A hypernuclei gives information on the strangeness changing weak baryon baryon interaction. The parity violation of the process has been studied by observing weak nonmesonic decay of polarized A hypernuclei. Study of the inverse process pn --+ pA gives much cleaner information on the process. Recent progress on the experimental study is presented.

1.1. Weak decay of A hypernuclei

Weak hyperon nucleon interaction can be studied in the weak nonmesonic decay (NMdecay) ofA hypernuclei. The NM-decay (A+n --+ n+n, A+p -+ p+n (q ,~ 400MeV/c)) is *representing a collaboration with S.

Scattering observables of the NN and YN interactions and nuclear-matter properties are investigated in a recent quark model developed for a unified description of the NN and YN systems. The model is formulated in the (3q)-( 39 ) resonating-group method, and incorporates the full Fermi-Breit interact
