Title: Ionization and fragmentation of solid C{sub 60} by femtosecond laser ablation

Abstract

Ionization and fragmentation of solid C{sub 60} dispersed on a silicon plate are investigated by femtosecond laser ablation. Bimodal mass distribution with large fragment ions C{sub 60-2n}{sup +} (0{<=}n{<=}11) and small fragment ions C{sub n}{sup +} (13{<=}n{<=}28), formation of dimer ion (C{sub 60}){sub 2}{sup +}, and delayed ionization of C{sub 60} have been observed as reported in gas phase experiments with nanosecond laser excitation. Metastable dissociation of small fragment ions C{sub n}{sup +} has been observed for the first time, which suggests different structures of fragment ions compared with those of well-studied carbon cluster ions. From these observations, strong coupling of laser energy to electronic degrees of freedom of solid C{sub 60} has been revealed for femtosecond laser ablation as compared with excitation in the gas phase.
