Abstract: We describe a method for measuring the electromagnetic form factors of the m D* meson at time-like momentum transfer in e+ e- annihilation. This is to study the joint angular distribution of the e+ e-γ* → D*+ D*-, D*+ → D0 π+, and D*-D0 π- processes. The magnitudes and relative phases of the charge, magnetic and quadrupole form factors can be determined. The method can also be applied to other vector particles.
