摘要：

Kinematically complete measurements for Coulomb dissociation of Li-11 into Li-9 + 2n 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 Li-11 has a peak, as anticipated in low-energy dipole resonance models, but a large post-breakup Coulomb acceleration of the Li-9 fragment is observed, indicating a very short lifetime of the excited state and favoring direct breakup as the dissociation mechanism.
