Photoelectron spectra of AgSin − (n = 3–12) clusters recorded with 266 nm photons.
Low-lying isomers of AgSin − (n = 3–12) clusters. The relative energies to the most stable isomers are listed under the geometric structures. The dark cyan spheres stand for silicon atoms and the red ones for silver atoms.
Comparison of the experimental photoelectron spectra of AgSin − (n = 3–12) clusters with their simulated DOS spectra. The simulations were conducted by fitting the distribution of the transition lines with unit-area Gaussian functions of 0.2 eV FWHM (Full Width at Half Maximum).
NPA charges on the metal atom of the most stable isomers of MSin − (M = Ag, Cu) clusters.
Relative energies, theoretical VDEs and ADEs of the low-lying isomers of AgSin − (n = 3–12) clusters, as well as the experimental VDEs and ADEs estimated from their photoelectron spectra. The isomers labeled in bold are the most probable isomers in the experiments.
