In an experiment measuring charmed-particle lifetimes with use of a hybrid-emulsion spectrometer in the wide-band neutrino beam at the Fermi National Accelerator Laboratory, 1248 neutrino and antineutrino interactions have been located. Twenty-three charged charm decay candidates have been reconstructed, from which we determine the lifetime of the D/sup + -/ to be 11.5/sub -3.5//sup +7.5/ x 10/sup -13/ s, that of the F/sup + -/ to be 1.9/sub -0.7//sup +1.3/ x 10/sup -13/ s, and that of the ..lambda../sub c//sup +/ to be 2.3/sub -0.6//sup +1.0/ x 10/sup -13/ s.
