In an experiment measuring charmed-particle lifetimes with a hybrid emulsion spectrometer, 1248 neutrino and antineutrino interactions produced by the wide-band beam at Fermi National Accelerator Laboratory have been located. Twenty-one candidates for the decay of neutral charmed particles are found. The lifetime for the D/sup 0/ based on the sixteen constrained events of this sample is measured to be 2.3/sup +0.8//sub -0.5/ x 10/sup -13/ sec.
