Abstract
Ablation of carbon clusters from a graphite surface exposed to 35 ps w ide 1064 nm wavelength, laser pulses of intensities of the order of 10 (14) W cm(-2) yields cluster ions in high charge states. Double and tr iple coincidence spectra of singly-charged atomic fragments resulting from spontaneous dissociation of C-n(q+) ions yield evidence that the kinetic energies released are much less than those calculated using ab intio configuration interaction methods.
