Resumen:
The nonmesonic weak decay spectra of light hypernuclei have been evaluated in asystematic way. As theoretical framework we adopt the independent particleshell model with three different one-meson-exchange transition potentials.Good agreement with data is obtained for proton and neutron kinetic energy spectraof $^4_Lambda$He, and $^5_Lambda$He, when the recoil effect is considered. The coincidence spectra of proton-neutron pairs are also accounted for quite reasonably,but it was not possible to reproduce the data for the neutron-neutron pair spectra.It is suggested that the $pi+K$ meson-exchange model with soft monopole form factorscould be a good starting point for describing the dynamics responsible for the decaysof these two hypernuclei. The $^4_Lambda$H~ spectra are also presented.
