| dc.description | For the energy absorption of atomic clusters as a function of the laser pulse duration we find a similar behavior as it has been observed for metallic clusters [Köller et al., Phys. Rev. Lett. {\bf 82}, 3783 (1999)]. In both situations there exists an optimum radius $R_{o}$ of the cluster for energy absorption. In the metallic case the existence of $R_{o}$ has been interpreted as a consequence of the collective oscillation of a delocalized electron cloud in resonance with the laser frequency. Here, we give evidence that in the atomic cluster the origin of $R_{o}$ is very different. Based on field assisted tunneling it can be related to the phenomenon of enhanced ionization as it occurs in small molecules. The dependence of $R_{o}$ on the laser frequency turns out to be the key quantity to distinguish the processes. | |
