 note = {We measured temporal variations of the distributions of C_2 and C_3 radical densities in carbon plumes produced by laser ablation of graphite in ambient He gas. Laser-induced fluorescence imaging spectroscopy was used for the measurement. The temporal variations of total numbers of C_2 and C_3 contained in plumes were evaluated by integrating the density distributions. The experimental observations have shown that the gas-phase production of C_2 is comparable to the direct production from the target, while C_3 is mainly produced in gas phase by three-body reactions between C and C_2 . In addition, we have discussed a scenario for the temporal evolution of heavy clusters (C_n with n≽4). The present results are useful for understanding initial formation processes of carbon clusters in laser-ablation plumes.},
