Electronic (one-photon) photodepletion spectra were recorded for gold cluster anions complexed with one xenon atom over the photon energy range 2.13.4 eV. Clusters were generated by pulsed laser vaporization and probed under collisionless molecular beam conditions. The spectra obtained are highly structured with the narrowest featuresassigned to individual electronic transitionshaving bandwidths of less than 40 meV. Time-dependent density functional theory predictions of optically allowed transitions for the most stableplanarisomers of the corresponding bare metal cluster anions are generally consistent with the experimental observation. ©2004 American Institute of Physics.
