superconductors. David Muller (Lucent Technologies Bell Laboratories) continued with apresentation on "Atomic-resolution electron energy loss spectroscopy in the scanningtransmission electron microscope: understanding the limits to scaling nano-transistors."Muller demonstrated that there is an electronic transition region from silicon to silicondioxide in the gate region of an MOS transistor even when the structural transition isatomically abrupt, which leads to a fundamental limit of about 0.7 nm on how thin thegate oxide can be.Berkeley Lab Director Charles Shank opened the Wednesday proceedings with his ownwelcome, noting the vitality of a field that has endured for 30 years and pointing out thegrowing importance of ultrafast time-resolved experiments in the femtosecond regime. Inthe following plenary lecture "Intermolecular Coulombic decay in clusters and weaklybound systems," Lorenz Cederbaum (Universitat Heidelberg) discussed a model for therapid decay that occurs by electron emission in inner-valence ionized molecular clusters,but not in monomers of species such as water. In the model, an efficient Coulombicmechanism transfers energy to neighboring monomers, thereby allowing electrons toescape. Ernst Bauer (Arizona State University) then spoke on "Spectromicroscopy:present and future." Bauer focused on the x-ray photoemission electron microscope(XPEEM), calling attention to both sychrotron-radiation excited measurements and theversatility possible with the addition of an electron source in the same instrument forLEEM and LEED measurements and, in separate projects at BESSY II and the ALS, thedevelopment of aberration-corrected electron optics for higher spatial resolution in theXPEEM.Plenaries on Thursday began with Yves Baer (University of Neuchatel) speaking on"High-resolution UV-photoemission of solids: success, limitations, and the future." Baerreviewed three examples: Kondo systems involving cerium, where it is important todistinguish bulk from surface effects, the strong electron-phonon interaction affecting theberyllium (0001) surface state, and the breakdown of the quasi-particle concept in a one-dimensional metal formed by linear chains of gold on a vicinal surface of silicon (111).Joseph Nordgren (Uppsala University) continued with a presentation on "X-ray emission
