I propose a new method to measure the magnetic moment parameter κ of the charged intermediate weak boson. T-odd asymmetries in the angular distribution of the secondary lepton in the process e+e- → Zγ, Z → ℓℓ are very sensitive to κ. The asymmetric are calculated in the lowest order from the absorptive part of one-loop diagrams.
