Abstract

We have theoretically investigated the stability of highly charged C60z + cations produced with an intense ultrashort laser pulse of λ ∼ 1800 nm. By calculating the energies relevant to the dissociation of C60z + such as the excess vibrational energy acquired upon sudden ionization, we find that C60z + up to z ∼ 12 can be produced as a stable or quasistable (μs-order lifetime) intact parent cation. We have also investigated the vibrational dynamics induced by a near-infrared pulse of λ ∼ 1800 nm. The results indicate that large-amplitude vibration with energy of >10 eV is induced in the delocalized hg(1)-like mode of C60z +.
