Abstract

We have studied the threshold production and decay angular distribution of neutral charmed mesons produced in e+e- annihilation. We find consistency with the expected spin values of 0 and 1 for the ground and excited states D and D*, respectively. We rule out the alternative spin assignment of 1 for the D and 0 for the D*.
