| Abstract: | In radiative decays of charged leptons induced by non-degenerate neutrino masses and consequent lepton flavour-mixing, the
dominant suppression factor at the 1-loop level is (Σ m

)/m
W

a being the mass of theath neutrino. We show that this suppression factor is presentin all orders in a class of models including the standard model. |
