  abstract     = {{In this paper, we address three major issues, look at their interaction and combination and present our results on how to arrive at solutions for these issues. The issues are: 1) supporting informal communication and atmosphere in organisations, 2) the role and potential of ambient displays in future work environments, and 3) the combination of mostly static artefacts that are integrated in the architectural environment with mobile devices carried by people. Our results can be considered as steps towards the design and realization of what we call “social architectural spaces” in the context of future work environments. These environments will be populated with a range of different smart artefacts that are designed to facilitate awareness and notification as well as informal communication. We address a range of spaces in office buildings including public spaces, e.g., in the hallway, the foyer, and the cafeteria that have not been the focus of research so far. In particular, we present two artefacts: the Hello.Wall, a wall-size large ambient display, and the ViewPort, a mobile handheld device. They are interacting with each other via wireless networks and different types of sensing technology. The artefacts and the software were developed in the EU-funded “Disappearing Computer”- project “Ambient Agoras: Dynamic Information Clouds in a Hybrid Worlds”.}},

In dieser Zeit kann sich das Licht nur etwa einen zehntel bis einen halben Millimeter ausdehnen. Die Fokussierung dieser Strahlung erzeugt elektrische Felder,
die denen im Innern eines Atoms entsprechen. 
Bei der Wechselwirkung von Clustern mit solchen L.aserpulsen sind interessante Effekte zu beobachten: Es entstehen in Bereichen niedriger Laserintensität mehrfach geladene Pt- und Pb-Cluster. Deren kleinste auftretende Größe kann mit den Voraussagen des Tröpfchenmodells verglichen werden. Direkt in dem Fokus der Laserstrahlung, dort wo die Materie den obigen extremen Feldern ausgesetzt wird, ist die Stärke der Anregung so groß, daß die Cluster vollständig
in hochgeladene Atome zerfallen. Es zelgt sich eine interessante Abhängigkeit der erreichbaren Aufladung der Atome (L.adungszustand) von der Länge des Laserpulses.

Ein einfaches Modell aus Epansion und optischer Respons des Clusters kann diesen Effekt qualitativ erklären.  Vergleichsmessungen an Kohlenstoff zeigen nicht dieses Verhalten. Zwingend notwendig scheint die Möglichkeit der kollektiven Anregung der Valenzelektronen von Metallclustern zu sein.}},

For small carbon clusters and fullerenes the abundance of charged species correlates with the laser power, while for metal clusters the ionization efficiency is additionally strongly affected by the chosen laser pulse width which may result in an enhanced up–charging of the metal particle. In the case of platinum atomic charge states up to z=20 are detected at a pulse duration of about 600 fs.

  abstract     = {{Positive and negative silver cluster ions are produced by sputtering of solid silver by 25 keV Xe+ bombaxdment. After mass selection, collinear ion beam depletion is used to measure absolute photofragmentation cross-sections in the photon energy range from ħω = 2.0 to 5.7 eV. Giant resonances are found which can be interpreted in terms of a collective electron oscillation. For spherical clusters (e.g., Ag19−, Ag21+) single resonances dominate the spectra, whereas deformation (e.g., Ag9−, Ag11+) induces a splitting into two components.}},
