Clustering has been long known to play an important role in the structure of light nuclei. We investigate the fragmentation mechanism reflecting the cluster structure of the ^<17>C. The breakup of the neutron-rich nuclei ^<17>C into ^8Li + ^9Li has been studied using a 44MeV/nucleon ^<17>C beam inelastically excited by ^<12>Ctarget. The clustering structure of is reflected in its fragmentation as the dynamical cluster breakup into ^8Li and ^9Li , depending on the incident energy. Excited states in ^<17>C were observed at 29.3±0.1 and 34.4±0.1MeV. This result would indicate that ^<17>C have a well-established cluster structure in the ground state.
