The longitudinal momentum distributions of 14C and 15C fragments from 16C breakup have been measured at 83 A MeV by means of recently-developed direct time-of-flight technique. The distributions are characterized by FWHM of 142±14 MeV/c and 90±9 MeV/c for 14C and 15C, respectively. A Glauber-type analysis performed for the 15C distribution gives the relative s-wave spectroscopic factor to be around 30%, which is smaller than that for the halo nucleus 15C where the s-wave is dominant. The two-neutron removal cross section is found to be larger than the one-neutron cross section.
