In an experiment measuring charmed-particle lifetimes with a hybrid emulsion spectrometer, 685 neutrino and antineutrino interactions produced by the wide-band beam at Fermi National Accelerator Laboratory have been located. These events have been carefully searched for visible decays. This Letter reports the seven neutral decays which are consistent with a D0 hypothesis and determine a lifetime of 1.00-0.31+0.52×10-13 sec for this charmed state.
