Neutral Pb clusters in the size range from a few tens of atoms up to similar to 100 atoms are studied using synchrotron-based photoelectron spectroscopy. The electronic structure is seen to differ increasingly from that of the solid when the cluster

Fragmentation of tributyltin chloride (TBTCl) vapour has been studied experimentally by means of time-of-flight mass spectrometry at the photon energy range of 9–25 eV of synchrotron radiation, at 21.22 eV of HeI as well as with 500 eV electron bea

Previously we reported an interionic Auger decay following the VUV resonant excitations of the metal atom in the alkali halide molecules. Opening and closing of the spectator Auger decay channel was found to strongly influence the lineshape of the pa

Cascade Auger transitions following the Xe 4d → 6p excitation have been studied both experimentally and theoretically. The low kinetic energy part from 2 to 30 eV of the resonance Auger spectra has been recorded with different photon bandwidths whi

The partial ion yield spectra of Xen+ ions (n = 1–8) were detected by an ion time-of-flight mass analyser in the photon energy range of 664–694 eV, and the branching ratios of ions following the 3d−15/2 ionization and the 3d5/2→ 6p resonance

The 2s photoionization and subsequent Auger transition cascade in atomic Si were studied by means of synchrotron-radiation-induced electron spectroscopy. After the 2s photoionization, the core hole states decay predominantly by a two-step Auger trans

Free nanoscale tin clusters in the average size range of a few tens up to similar to 500 atoms are studied by means of valence and core-level photoelectron spectroscopy. A self-consistent picture arises from comparison of the work functions derived f
