We report the measurement of the lifetime of the D/sup 0/ meson. The direct observation of the decay vertex distribution in the process D/sup 0/ ..-->.. K/sup -/..pi../sup +/ was made using a vertex chamber installed in the HRS detector at PEP. The measured lifetime is found to be tau/sub D/sup 0// = .42 +- .09 +- .06ps. 5 refs., 4 figs.
