Book Description
The rate for the three-body recombination of an electron and an oxygen atomic ion, with a nitrogen atom acting as third body that takes up the excess energy, was calculated by the quantum mechanical distorted wave method. The calculation was performed numerioally on IBM 7090 computers for electron and heavy particle energies below 1 ev, and for the electron captured into states characterized by principal quantum numbers n = 6, 10. The results for the recombination coefficient summed over all possible orbital quantum numbers of the bound electron are 10-28cm6/sec for n = 6 and 10-26 cm6/sec for n = 10. (auth).

Book Description
This volume contains the proceedings of the third Euroconference on Atomic Phys ics at Accelerators (APAC 2001), with the title Stored Particles and Fundamental Physics. It was held in Aarhus, Denmark, from September 8 to 13 at the Marselis Hotel located near the beach and the Marselis Woods outside Aarhus, but some of the activities took place at the Department of Physics, University of Aarhus. The conference was sponsored by the Commission of the European Union (Contract No. ERBFMMACT980469) and also by the Danish Research Foundation through ACAP (Aarhus Center for Atomic Physics). The meeting was focused on the application of storage rings for atomic physics, and there are two fairly small rings in Aarhus, ASTRID (Aarhus STorage Ring for Ions,Denmark) and ELISA (ELectrostatic Ion Storage ring, Aarhus). The research at these rings has contributed to the strong position of European Science in this field. Both rings are designed according to unique concepts. ASTRID is a dual purpose ring, which half the time stores electrons for the generation of low-energy synchrotron radiation. The storage of negative particles has also been a unique feature for the application of ASTRID as an ion storage ring.

Book Description
The monograph is devoted to the relatively new and fast developing field of cluster physics. It is based on talks given at the Cluster Workshops, which were held in Pushchino in 1995 and 1996. The reports focus not only on the fundamental physical properties of clusters such as their geometric and electronic structure, as well as optical, thermal and magnetic properties, but also on a broad spectrum of their potential applications. These include nucleation and growth of small particles, fabrication of new materials with predefined properties (cluster-assembled and nanostructures). Some aspects of simulations and calculations of small particles and clusters are also discussed.We hope that our monograph will be of interest to a broad range of readers who will be able to sense the excitement of the talks.

Book Description
This book focuses on the characteristics of optical radiation, or a spectrum, emitted by various plasmas. In plasma, the same atomic species can produce quite different spectra, or colours, depending on the nature of the plasma. This book gives a theoretical framework by which a particular spectrum can be interpreted correctly and coherently. The uniqueness of the book lies in its comprehensive treatment of the intensity distribution of spectral lines and the population density distribution among the atomic levels in plasmas. It is intended to provide beginners with a good perspective of the field, laying out the physics in an extremely clear manner and starting from an elementary level. A useful feature of the book is the asterisked sections and chapters which can be skipped by readers who only wish to gain a quick and basic introduction to plasma spectroscopy. It will also be useful to researchers working actively in the field, acting as a guide for carrying out experiments and interpreting experimental observations.

Book Description
Advances in Nuclear Science and Technology, Volume 3 provides an authoritative, complete, coherent, and critical review of the nuclear industry. This book presents the advances in the atomic energy field. Organized into six chapters, this volume begins with an overview of the use of pulsed neutron sources for the determination of the thermalization and diffusion properties of moderating as well as multiplying media. This text then examines the effect of nuclear radiation on electronic circuitry and its components. Other chapters consider radiation effects in various inorganic solids, with emphasis on the investigation of variations effected in the mechanical and optical crystalline properties. This book discusses as well several methods for solving various problems in reactor theory. The final chapter deals with several types of pulsed neutron sources in use and speculates on improvements that may be expected in their performance. This book is a valuable resource for design engineers and neuron physicists.
