 Simple and coincidence spectra of the nonmesonic weak decay of light hypernuclei have beenevaluated in a systematic way for the first time. We have only considered 1nucleon induced processes, neglecting entirely the events induced by two-nucleon  emission, as well as the effects of the Final State Interactions. As the theoretical frameworkwe have used the Independent Particle Shell Model with three different parametrizations for the transition potential. The comparison with data strongly suggests that the soft π +K exchange model could be a good starting point to describe the decay dynamics in the of s-and p-shell hypernuclei.
