The Advanced Study Institute of which this volume is the proceedings was held at the University of Exeter during 24 August to 6 September 1975. There were seventy participants of whom eighteen were lecturers and members of the advisory committee. All NATO countries except Holland, Iceland and Portugal were re presented. In addition a small number of participants came from non-NATO countries Japan, Ireland and Switzerland. An aim of the organising committee was to bring together scientists of wide interests and expertise in the defect structure of insulators and semiconductors. Thus major emphases in the pro gramme concerned the use of spectroscopy and microscopy in revealing the structure of point defects and their aggregates, line defects as well as planar and volume defects. The lectures revealed that in general little is known of the fate of the interstitial in most irradiated solids. Nor are the dynamic properties of defects under stood in sufficient detail that one can state how point defects cluster and eventually become macroscopic defects. Although this book faithfully reproduces the material covered by the invited speakers, it does not really follow the flow of the lectures. This is because it seemed advisable for each lecturer to provide a single self-contained and authoritative manuscript, rather than a series of short articles corresponding to the lectures.

This extensive survey covers defects in nonmetals, emphasizing point defects and point-defect processes. It encompasses electronic, vibrational, and optical properties of defective solids, plus dislocations and grain boundaries. 1985 edition.

Strutural Analysis of Point Defects in Solids introduces the principles and techniques of modern electron paramagnetic resonance (EPR) spectroscopy essentialfor applications to the determination of microscopic defect structures. Investigations of the microscopic and electronic structure, and also correlations with the magnetic propertiesof solids, require various multiple magnetic resonance methods, such as ENDOR and optically detected EPR or ENDOR. This book discusses experimental, technological and theoretical aspects of these techniques comprehensively, from a practical viewpoint, with many illustrative examples taken from semiconductors and other solids. The nonspecialist is informed about the potential of the different methods, while the researcher faced with the task of determining defect structures isprovided with the necessary tools, together with much information on computer-aided methods of data analysis and the principles of modern spectrometer design.

This volume provides a detailed examination of the physical basis for EPR imaging and in vivo EPR spectroscopy, experimental arrangements, and data analysis. The EPR imaging methods described include continuous wave, spin-echo-detected and ENDOR-detected EPR with constant, stepped, modulated, and pulsed magnetic field gradients. Applications described include inhomogeneous materials, diffusion kinetics, reaction kinetics, orientation of liquid crystals, microwave distributions, magnetic field distributions, superconductors, radiation damage, and defects in solids. The book also covers other topics important to in vivo studies, including in vivo EPR spectroscopy, low-frequency EPR, state-of-the-art low-frequency EPR instruments, achievable sensitivity, and spin labels. The book will be of great interest to graduate students, researchers, and medical instrument developers who use EPR, as well as clinicians and chemists interested in the relationship between in vivo radicals (such as superoxide and diseases).

The Cargese Summer Institute 1975 on Weak and EZeotromagnetio Interaotions at High Energies was organized by the Universite Pierre et Marie Curie (M. LEVY et J.L. BASDEVANT)~ the KathoZieke Universiteit te Leuven (R. GASTMANS) and the Universite CathoZique de Louvain (D. SPEISER~ J. WEYERS) who made in 1973 the first oon taots with some Zeoturers~ who~ on the advioe of NATO joined their efforts and worked in oommon. It was the 16th Summer Institute rd heZd at Cargese and the 3 one organized by the two departments of TheoreticaZ Physios at Leuven and Louvain-Za-Neuve. When the two groups decided (independentZy) on the subjeot of the sohooZ~ they oouZd not know how Zuoky their ohoioe eventuaZZy wouZd turn out to be : rareZy has it being possibZe to present an audienoe with suoh a great number of new and deoisive disooveries who are Zikely to stimuZate the imagination of theoreticians and the researoh projeots of experimentaZists aZike. Suoh were the decisive oonfirmation of the neutraZ ourrents~ the di-muon events~ the sZowZy deoaying new partioZes~ eto. The organizers were grate JUZ indeed that they oouZd find physioists from aZmost alZ great oenters of high energy physios Who had themseZves participated in these disooveries.
