摘要：

The result of the calculation of the charged lepton decay process with flavour violation and emission of two photons l(i)+/- --> l(j)+/- gamma-gamma in the framework of the standard model with fermion mixing is given. The calculations were performed under the condition that m2(2) << m1(2) << n(w)2. It is shown that the ratio of the two-photon and one-photon decay probabilities Br = W-gamma-gamma/W-gamma is independent of either the mixing angles, or the virtual lepton masses, but depends only on the experimental conditions of the registration of the decay products.
