    "abstract": "We calculate the two-photon ionization of clusters for photon energies near\nthe surface plasmon resonance. The results are expressed in terms of the\nionization rate of a double plasmon excitation, which is calculated\nperturbatively. For the conditions of the experiment by Schlipper et al., we\nfind an ionization rate of the order of 0.05-0.10 fs^(-1). This rate is used to\ndetermine the ionization probability in an external field in terms of the\nnumber of photons absorbed and the duration of the field. The probability also\ndepends on the damping rate of the surface plasmon. Agreement with experiment\ncan only be achieved if the plasmon damping is considerably smaller than its\nobserved width in the room-temperature single-photon absorption spectrum.",
