Abstract：
In the first part of this note, we have analysised phenomenologically the magnetic moment of W ^±bosons. After getting their bare μ _Wand Q _Wfrom electromagnetic vertex expressions, we have shown from effective Lagrangian that on what cases W ^±mesons would get anomalous magnetic moment and electric quadrupole moment. In the second part, we have discussed the processes γ+e ^-→W ^-+v by high energy electrons colliding with hard circular polarized photons, we have calculated the dσ/dt,σ(s) and the asymmetry coefficients A(s), these results show that one can determine the magnetic moment of W ^±mesons unambigously from measuring the energy dependence of these quantities.
