  The Lambda decay rates in nuclei has been calculated in ref. 1 using the
Propagator Method in Local Density Approximation. We have studied the
dependence of the widths (including the one for the two-body induced process
Lambda NN -> NNN) on the N-N and Lambda-N short range correlations. Using a
reasonable parametrization of these correlations, as well as realistic nuclear
densities and Lambda wave functions, we reproduce, for the first time, the
experimental non-mesonic widths from medium to heavy hypernuclei.
