Rapid increases of knowledge in the "Golden Age of Astronomy" have necessitated the publishing of a new edition of the Astronomy and Astrophysics volumes of the Landolt-Boernstein. The title is now "Astronomy, Astrophysics, and Cosmology."
Vols. III/17a-i and III/22a, b (supplement) on semiconductor physics and technology have been published earlier, the latter covering new data on the technologically important group IV elements and III-V, II-VI and I-VII compounds only. The wealth of further data from the last decade is now being critically evaluated by over 30 well-known experts in the field of semiconductors. To meet the demands of todays scientists and to offer a complete overview on semiconductor data all data available so far are published in the following way: a series of five subvolumes covers only the supplementary data to volumes III/17 and 22. Enclosed to each subvolume, a CD-ROM contains a complete, revised and update edition of all relevant data. For each individual substance the information is presented in userfriendly documents, containing data, figures and references. Easy access to the documents is provided via substance and property keywords, listings and full text retrieval.
Parameters of neutron resonances are finding increasing interest, not only for scientific problems like the understanding of astrophysical processes but even more so for applications. For the construction and the safety of conventional nuclear reactors such data are essential and for new developments like the thorium-uranium cycle or for nuclear waste transmutation they are indispensible. Since the last publication of neutron resonance parameters at Landolt-Börnstein in 2004, the quality and precision of the data has been considerably improved, partly by the operation of new neutron spectrometers, e.g., the CERN time-of-flight facility recently put into operation and also by the use of new carefully designed neutron capture detectors. Volume I/24 contains neutron resonance parameters for the nuclear levels of 356 nuclei with Z ranging from 1 to 98 compiled by two eminent experts in the field. Again a considerable effort was made in comparing data from different sources in order to solve some previous discrepancies and establish 'best values', one of the main characteristics of Landoldt- Börnstein publications. In order to compare the data from different sources a comparison of the various experimental installations has been given. In view of the large amount of data the parameters for only the most important resonances are given in the printed version. However, the data for all resonances are available online at www.springerlink.com (DOI: 10.1007/978-3-540-87866-7). Neutron resonance parameters of many nuclei were previously published by Landolt-Börnstein in Volumes I/16B and I/16C.
1 Introduction Data extract from Landolt-Börnstein IV/17: Static Dielectric Constants of Pure Liquids and Binary Liquid Mixtures 1. 1 Selection of data This supplement updates Landolt-Börnstein's New Series Group IV (Physical Chemistry) Volume 6, Static Dielectric Constants of Pure Liquids and Binary Liquid Mixtures, published in the year 1991 [1991WOH1]. The update provides experimental data published in the years 1991 to 2006. The ?nal date for including data was December, 31st, 2006. Specialization and selection of data for this new update follows the intentions of the original volume. The focus is on non-electrolyte systems, and only data for pure liquids and binary liquid mixtures at normal pr- sure (or in some single cases at the saturation vapor pressure) were taken into account for this volume. No data at higher pressures were collected, no data for the gaseous state, and no data for dielectric relaxation processes at higher frequencies have been included. For mixtures, this data collection is restricted to binary liquid mixtures, i. e. no ternary systems and also no solutions of any solids, salts, electrolytes, polymers are included here. At least, also molten metals and metallic alloys, molten salts, molten glasses and other hi- temperature melts were not taken into account. As the amount of data collected between 1991 and 2006 exceeds the available space for printing by far, the volume has an electronic version containing additional data which is available on www. landolt-boernstein.
Metallic amorphous materials are of high strength, high corrosion resistance, high permeability and other industrially important and useful properties. Furthermore, new metallic materials can be produced from metallic amorphous materials by proper crystallization processes, usually heat treatment, to meet the various industrial demands. In subvolume A, 8327 points of formation data of 1532 ternary amorphous alloys consisting of 351 ternary systems have been extracted, classified and evaluated. Preparation methods, atmosphere for preparation of amorphous alloys, sample form and size and phase identification methods are provided. Composition data are given in phase diagrams and tables. Subvolume B is in preparation.
Atomic or point defects are disturbances of the periodicity of the crystal lattice extending over only a few atomic distances. Many physical and mechanical properties of solids are sensitive to their presence. Furthermore other defects which are crucial to material behaviour are influenced by their interaction with atomic defects. A detailed knowledge of production mechanisms and properties of point defects is therefore essential for assessing and for understanding the atomistic as well as the macroscopic behaviour of materials. As a result of the use of new research methods in recent years, such information is now available for almost all pure metals, for many dilute alloys and for some concentrated alloys. However, a critical and comprehensive collection of these data has so far been missing. The aim of the present volume is to close this gap by sifting, evaluating and compiling data on vacancies and self-interstitial atoms in solid metals. A chapter on the element helium is included because of the exeptional position of He as an "alloying" element and its role in radiation damage phenomena.
