    Gas Phase and Particle Diagnostic of Hmdso Plasmas by Infrared Absorption Spectroscopy

    FTIR spectroscopy has been applied to a radio-frequency discharge in hexamethyldisiloxane (HMDSO) diluted with oxygen and helium, as typically used for industrial SiOx, deposition. By measuring the infrared absor...

    Size-dependent light emission from mass-selected clusters

    The emission of photons in the visible wavelength range from mass-selected Ag+ n, Cu+ n, Pt+ n and Pd+ n ( ) clusters is observed. Photons are detected ...

    R-Parity, the Supersymmetric Standard Model and the Phenomenology of Supersymmetry

    Although it involves a spin-1/2 generator, the supersymmetry algebra cannot be used to relate directly known fermions and bosons. Nevertheless, and despite all appearances of the contrary, supersymmetry may still...

    Photoemission from Size-Selected Pt-Clusters Deposited on Silver Films

    When atoms are brought close together to form a solid their outer wave functions overlap and the energy levels of the individual atoms broaden and become the energy bands of condensed matter. The observation o...

    Electronic structure of deposited monosized metal-clusters

    Monosized Pt- and Au-clusters deposited on silica substrates are analyzed by photoelectron spectroscopy. The 4f-core-level energies and the valence electronic states depend on the cluster size and on the element....

    Abnormally large deuterium uptake on small transition metal clusters

    Deuterium uptake experiments on gas phase transition metal cluster cations of Ni, Pt and Rh show that the small (< 10 Å dia.) clusters can bind many (up to 8) deuterium atoms per metal atom in the cluster, in ...

    Supersymmetry, Particle Physics and Gravitation

    Supersymmetry is a beautiful symmetry between bosons and fermions, although there is no evidence of it in Nature1. This does not mean that supersymmetry is not present, but that it must be well hidden. Super symm...
