    • 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 ma2)/mW2,ma 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.
