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 ^*+→ D ⁰π ⁺, and D ^*-→ D⁰π ^-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.
