Photoabsorption of silver cluster cations in an ion trap: nonlinear action spectra multi-photon dissociation directly measured linear absorption spectra.

We report photodissociation processes and spectral measurements upon photoabsorption of size-selected cationic silver clusters, Ag, stored in an ion trap. The experiment shows that small clusters ( ≲ 15) dissociate upon one-photon absorption, whereas larger ones require multiple photons up to five in the present study. The emergence of multi-photon processes is attributed to collisional cooling in the presence of a buffer helium gas in the trap, which competes with size-dependent dissociation rates.
