We determine the resonant substructure of D0K decays using a five-dimensional maximum-likelihood technique to extract the relative fractions and phases of the amplitudes contributing to this final state. We find that two-body decay modes account for at least 76% of all decays. We obtain branching ratios for several decay modes including B(D0K-a1+) =(9.0±0.9±1. 7)%, B(D0K»0*0)=(1.9±0.3±0.7)%, and B(D0K1(1270)) =(1.8±0.5 ±0.8)%. For the decay mode D0K»0*0, the K» *0 and 0 are found to be polarized with their spins oriented in the direction of their motion as seen from the D0 frame.
