We compute one- and two-nucleon kinetic-energy spectra and opening-angle distrbutions for the nonmesoinic weak decay of several hypernuclei, and compare our results with some recent data. The decay dynamics is described by transition spotentialsof the one-meson-echange type, and the nuclear structure aspects by two versions of the independent particle shell model (IPSM). In version IPSM-a, the hole states are treated as stationary, while in version IPSM-b the deep-hole ones are considered to be quasi-stationary and are described by Breit-Wigner distributions.
