The knowledge of the interactions of photons with hadrons has considerably improved with the study of high-energy lepton-proton collisions at HERA. The results on the partonic interactions of photons are summarized in comparison with photon-nucleon, two-photon, and proton-antiproton experiments.

The first five years of operation of the two multi-purpose experiments ZEUS and H1 at the HERA electron--proton storage ring facility in Hamburg, Germany have opened a new era in the study of diffractive vector-meson production in high-energy photon--proton interactions. This book provides readers who have a general knowledge of the concepts and experimental techniques of elementary particle physics with the information necessary to assess the status of the new investigations prior to the end of 1996. The measurements are placed in the rich historical context of earlier studies of photo- and...

This book presents an overview of the current understanding of the physics of zero-dimensional semiconductors. It concentrates mainly on quantum dots of wide-gap semiconductors, but touches also on zero-dimensional systems based on silicon and III-V materials. After providing the reader with a theoretical background, the author illustrates the specific properties of three-dimensionally confined semiconductors, such as the size dependence of energy states, optical transitions, and dephasing mechanisms with the results from numerous experiments in linear and nonlinear spectroscopy....

From Coherent Tunneling to Relaxation is an impressive review of ten years of progress in our understanding of interacting tunneling systems. The dielectric and elastic response of (111) off-center impurities in alkalide halides is investigated in detail and the coherent motion of an impurity pair is discussed in view of recently observed rotary echoes. The low-temperature properties of defect crystals with an impurity concentration higher than 100 ppm are reviewed and the dipolar interaction is shown to drive the cross-over to relaxational dynamics. This comprehensive presentation of the...

Studying the interactions between heavy hydrogen isotopes and hydride forming metals or intermetallic compounds (IMC) is of importance for both fundamental and applied sciences. These systems offer, for example, the possibility of technical hydrogen isotope separation due to their considerable isotope effects. In addition, quite a lot of problems of hydrogen recovery, hydrogen purification, and tritium storage can be solved. This review deals with theoretical aspects of the interaction of heavy hydrogen isotopes with metals and IMC, and contains detailed information on phase and isotopic...

Time-Resolved Light-Scattering from Excitons investigates exciton states in semiconductors and their relaxation processes by time-resolved light-scattering.
The reader will gain both a clear understanding of the theoretical aspects of this method and profound knowledge of the experimental state-of-the-art. The development of quantum-beat spectroscopy for excitons is also discussed.

This completely revised and enlarged English edition of the original Russianbook deals with the identification and separation of charged particles in high energy physics experiments. Proportional drift and streamer chambers as well as ionization measurements with cloud, spark, and ionization chambers are discussed. Both scientists and advanced undergraduate students specializing in high energy or nuclear physics will find useful information for planning and performing ionization measurements and their analyses.

Surface Scattering Experiments with Conduction Electrons shows how this process can be used to investigate surface processes of thin metal films. Since a thin film is in one direction of a size comparable to the mean free path of the conduction electrons, such a film is both substrate and sensor and must be characterized by other surface-analytical methodsas demonstrated here. Also discussed is how the dc-resistivity measurement permits the study of surface processes such as adsorption, desorption, and surface diffusion up to crystalline growth. The in situ observation of epitaxial growth...

This book deals with the application of grazing angle x-ray and neutron scattering to the study of surface-induced critical phenomena. With the advent of even more advanced synchrotron radiation sources and new sophisticated instrumentation this novel technique is expected to experience a boom. The comprehensive and detailed presentation of theoretical and experimental aspects of the scattering of evanascent x-ray and neutron waves inside a solid makes this book particularly useful for tutorial courses. Particular emphasis is put on the use of this technique to extract microscopic information...
