We compare two most relevant loop induced muon number violating processes, μ--> e γand μ-e conversion in nuclei, in constraining new physics. Because of much richer structure of the latter process it may be enhanced with respect to μ--> e γby a large ln(m2μ/Λ2), where Λ is the scale of the new physics. After model-independent considerations we present two examples constraining the R-parity violating couplings of MSSM and the off-diagonal couplings of the doubly charged Higgs bosons from the non-observation of μ-e conversion.
