Abstract:
Synchrotron radiation in the energy range between 6 and 30 eV was used to study the photon-stimulated field desorption (PSFD) from a water covered Ag-field emitter. Above a threshold energy of 7.4 eV (extrapolated for zero electric field) a variety of protonated water clusters (H2O)n⋅H+, n=1,...,15, are observed. The influence of the surface temperature, electric field, photon energy, and photon flux on the PSFD spectra are measured. Under certain experimental conditions the predominance of the magic cluster ion (H2O)4⋅H+ is observed.
