Monodispersed metal clusters in solid matrices: A new experimental setup
We describe a new experimental setup for the production of samples of metal clusters embedded in matrices stable at ambient conditions. The cluster ions are generated in the gas phase and codeposited fragmentation-free together with the evaporated matrix. Mean cluster sizes range from a few to many thousands of atoms. For small clusters (n < 20) mass selection is possible, larger clusters are d...
متن کاملFormation, deposition and examination of size selected metal clusters on semiconductor surfaces: An experimental setup
An instrument designed to investigate the chemical behavior of size selected metal clusters on semiconductor surfaces is described. The clusters re formed using laser vaporization, mass selected in a magnetic mass analyzer and deposited on TiO2 substrates under UHV conditions with + + mpact energies ranging from ≤1 to >100 eV/atom. Intensities of mass selected Aun and Agn clusters range from 0....
متن کاملExperimental and computational studies of alkali-metal coinage-metal clusters.
Coinage and alkali metal mixed clusters, M4Na- (M = Cu, Au) have been investigated experimentally using photoelectron spectroscopy and computationally at correlated ab initio levels. The related Cu4Li-, Ag4Li-, Ag4Na-, and Au4Li- clusters as well as the neutral Cu4Li2 and Cu4Na2 clusters have also been studied computationally. The calculations show that the two lowest isomers of the negatively ...

متن کاملA new compact solid-state neutral particle analyser at ASDEX Upgrade: Setup and physics modeling.
At ASDEX Upgrade (AUG), a new compact solid-state detector has been installed to measure the energy spectrum of fast neutrals based on the principle described by Shinohara et al. [Rev. Sci. Instrum. 75, 3640 (2004)]. The diagnostic relies on the usual charge exchange of supra-thermal fast-ions with neutrals in the plasma. Therefore, the measured energy spectra directly correspond to those of co...
