A detailed study of angular distributions arising from DD-bar, D*D-bar, D-bar*D, and D*D-bar* production at ..sqrt..s-bar=4.028 GeV is made, including the subsequent decays D*..-->..D..pi.. and D*..-->..D..gamma... The production amplitudes are unique except for the D*D-bar* 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*..-->..D..pi../sup 0/ and D*..-->..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.
