THE WEAK DECAYS OF LIGHT HYPERNUCLEI

There has been recent progress on both theoretical and experimental fr ontiers to constrain models of weak interactions between baryons. The status of the analysis of He-4,5(Lambda) decay rates is discussed, com paring new results with other recent and old measurements. In addition to total decay widths, kinetic energy distributions and some prelimin ary coincidence spectra are presented. These coincidences have proven to be essential to the interpretation of the weak-decay processes. In light of these new results, there is now consensus that complementary measurement of the decays of H-4(Lambda) is essential to address some basic questions, such as the validity of the Delta I = 1/2 rule for nu cleon-stimulated weak decay [1-5]. Prospects for such a measurement ar e also discussed.
