We have performed shell-model calculations starting from the CD-Bonn free nucleon-nucleon (N N) potential and making use of a new approach for the calculation of the effective interaction. This consists in deriving from the N N potential a low-momentum effective potential V low−k , defined within a given cutoff momentum Λ. Being a smooth potential it can be used directly in nuclear structure ca...

We re-examine the puzzling π emission from the weak decay of 4ΛHe and propose an explanation in terms of a three–body decay of the virtual Σ. Such a resolution of the π decay puzzle is consistent with the calculated Σ probability in light Λ hypernuclei as well as the experimentally observed π energy spectrum and s–wave angular distribution.
