摘要：

We show that the experimentally observed spectra of optical absorption of sodium cluster ions can be explained in the framework of the same random-matrix model, that has been employed earlier [Phys. Rev. Lett. 75, 220 (1995)] for the ground-state properties of alkali-metal clusters. This approach reveals the effect of cluster symmetry ''on average'' on the optical-absorption profiles, describes their temperature dependence, and predicts the line shapes of two-photon absorption.
