A detailed study of angular distributions arising from D{anti D}, D* anti D} , and D*{anti D}* production at {radical}s= 4.028 GeV is made, including the subsequent decays D*{yields}D{pi} and D* {yields} D{gamma}. The production amplitudes are unique except for the D*{anti D}* case, where there are two p-wave amplitudes (S = 0, 2) and one small f-wave amplitude (S = 2). It is shown that observations of the angular distributions and correlations of the {pi}{sup 0}'s and {gamma}'s from the D* {yields} D{pi}{sup 0} and D* {yields} D{gamma} decays provide an effective way of measuring the p-wave amplitudes. These amplitudes are a reflection of the underlying hadronic interactions among the charmed and uncharmed quarks.
