  We study the constraints on flavour violating terms in low energy SUSY coming
from several processes as li -> lj gamma, li -> lj lj lj and mu -> e in Nuclei.
We show that a combined analysis of the processes allows us to extract
additional information with respect to an individual analysis of all the
processes. In particular, it makes possible to put bounds on sectors previously
unconstrained by li -> lj gamma. We perform the analysis both in the mass
eigenstate and in the mass insertion approximations clarifying the limit of
applicability of these approximations.
