Kinematically complete measurements for Coulomb dissociation of n Li into 9 Li + 2« were made at 28 MeV/nucleon. The n-n correlation function suggests a large source size for the two-neutron emission. The electromagnetic excitation spectrum of n Li has a peak, as anticipated in low-energy dipole resonance models, but a large post-breakup Coulomb acceleration of the 9 Li fragment is observed, indicating a very short lifetime of the excited state and favoring direct breakup as the dissociation mechanism.
