“…Over the last couple of decades there have been several gas-phase studies of isolated polyanions using photoelectron spectroscopy. [16][17][18][19] This work has revealed that polyanions exhibit a distinct electronic structure compared to monoanions, characterized by the presence of a repulsive Coulomb barrier (RCB). 17,[20][21][22][23][24] In polyanions the interplay between long range Coulomb repulsion and short range attractive forces, result in the RCB to electron detachment, which in turn causes the characteristic low electron kinetic energy (eKE) cut-off observed in the photoelectron spectra of polyanions.…”

“…The falling edge at higher binding energies originates from the presence of a Coulomb barrier, which prevents direct emission of low energy electrons. 48,49 However, by means of tunneling through the barrier, electrons with lower energy exit the cluster and contribute to the spectrum. The impact of the Coulomb barrier on the left-hand side of the spectrum is illustrated, when recording data at higher photon energies, e.g.…”

“…By using tunable laser pulses, wavelength-dependent photoelectron spectroscopy is realized, which enables the study for, e.g. Coulomb barriers, 48 detachment energies, 42 sequential multiphoton detachment, as well as the optical response. In contrast to Penning traps, the storage capabilities of rf ion traps give access to much larger clusters.…”
