摘要：

In e(+)e(-) collisions using the CLEO detector, we have studied the decay of the D-0 to the final state K(S)(0)pi(+)pi(-) with the initial flavor of the D-0 tagged by the decay D*+-->D(0)pi(+). We use the Dalitz technique to measure the resonant substructure in this final state and clearly observe ten different contributions by fitting for their amplitudes and relative phases. We observe a K-*(892)(+)pi(-) component which arises from doubly Cabibbo suppressed decays or D-0-(D-0) over bar mixing.
