Resum
We present an update of the one-meson-exchange (OME) results for the weak decay of s- and p-shell hypernuclei [A. Parreño, A. Ramos, and C. Bennhold, Phys. Rev. C 56, 339 (1997)], paying special attention to the role played by final state interactions between the emitted nucleons. The present study also corrects for a mistake in the inclusion of the K and

With the most up-to-date model ingredients, we find that the OME approach is able to describe very satisfactorily most of the measured observables, including the ratio
