FIGURE 9.2 Comparison of TOF mass spectra obtained by one-photon ioniza-
tion (1PI) and multi-photon ionization (MPI) of laser ablated graphite in the He
buffer gas.
FIGURE 9.3 Ionization energies (E i ) of carbon clusters plotted as a function of the
carbon number (n). The horizontal line indicates the energy of the ninth harmonics
of a Nd:YAG laser.
