We compute one- and two-nucleon kinetic-energy spectra andopening-angle distributions for the nonmesonic weak decay ofseveral hypernuclei, and compare our results with some recentdata. The decay dynamics is described by transition potentials ofthe one-meson-exchange type, and the nuclear structure aspects bytwo versions of the independent-particle shell model (IPSM). Inversion IPSM-a, the  hole states are treated asstationary, while in version IPSM-b the deep-hole ones areconsidered to be quasi-stationary and are described byBreit-Wigner distributions.
