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.
