Book Description
Experimental Neutron Resonance Spectroscopy deals with the experimental technique of neutron resonance spectroscopy. Pulsed accelerator time-of-flight spectrometers and gamma rays from neutron capture in resonances are discussed. Total neutron cross section measurements are presented, along with neutron scattering and capture cross-section measurements and measurements on fissile nuclides. This book is comprised of five chapters and begins with an introduction to pulsed accelerator time-of-flight spectrometers with moderated continued neutron spectra, together with the pulsed Van De Graaff. Experimental techniques used for neutron cross section measurements, including detectors and data acquisition equipment, are then outlined. Scattering measurements and capture measurements as well as gamma-ray spectra from the capture of neutrons in resonances are considered. The final chapter focuses on the detailed and varied experiments that have been performed on the complicated fission process, together with the parameters of the resonances of the fissile nuclides. This monograph will be a useful resource for spectroscopists and physicists.

Book Description
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.

Book Description
This publication addresses recent developments in neutron generator (NG) technology. It presents information on compact instruments with high neutron yield to be used for neutron activation analysis (NAA) and prompt gamma neutron activation analysis in combination with high count rate spectrometers. Traditional NGs have been shown to be effective for applications including borehole logging, homeland security, nuclear medicine and the on-line analysis of aluminium, coal and cement. Pulsed fast thermal neutron analysis, as well as tagged and timed neutron analysis, are additional techniques which can be applied using NG. Furthermore, NG can effectively be used for elemental analysis and is also effective for analysis of hidden materials by neutron radiography. Useful guidelines for developing NG based research laboratories are also provided in this publication.

Book Description
E.U. Condon's major contributions were in atomic and molecular physics and spectroscopy; his book with G.H. Shortley on The Theory of Atomic Spectra dominated the field of spectroscopy for half a century and remains an invaluable reference. He also played an important role in the institutions of American science. He served for many years as the editor of Reviews of Modern Physics, and with Hugh Odishaw he edited the still widely used Handbook of Physics. After World War II, Condon became director of the National Bureau of Standards (now NIST), and helped to make it one of the premier research laboratories in the physical sciences in the world. The Selected Scientific Papers reprint many of the most important contributions Condon made to atomic physics, quantum theory, nuclear physics, condensed-matter physics and other fields. The Selected Popular Writings contain articles he wrote on technical topics for such journals as The American Journal of Physics, Science, and Nature, as well as reflections on education, UFO's, and other topics.

Book Description
Atlas of Neutron Resonances: Resonance Properties and Thermal Cross Sections Z= 1-60, Sixth Edition, contains an extensive list of detailed individual neutron resonance parameters for Z=1-60, as well as thermal cross sections, capture resonance integrals, average resonance parameters and a short survey of the physics of thermal and resonance neutrons. The long introduction contains: nuclear physics formulas aimed at neutron physicists; topics of special interest such as valence neutron capture, nuclear level density parameters, and s-, p-, and d-wave neutron strength functions; and various comparisons of measured quantities with the predictions of nuclear models, such as the optical model. As in the last edition, additional features have been added to appeal to a wider spectrum of users. These include: spin-dependent scattering lengths that are of interest to solid-state physicists, nuclear physicists and neutron evaluators; calculated and measured Maxwellian average 5-keV and 30-keV capture cross sections of importance to astrophysicists involved in nucleosynthesis modeling; s-, p-, and d-wave average radiative widths; and, nuclear level density parameters. - Provides a comparison of average resonance parameters with optical model calculations and with the generalized Landau-Fermi model - Presents scattering radii for various partial waves from the analysis of total neutron cross sections in the keV to MeV energy region - Includes a brief review of sub-threshold fission - Examines consistent treatment of average neutron parameters with values from the resolved resonance region
