Download or read book Neutron Cross Sections written by S Mughabghab and published by Elsevier. This book was released on 2012-12-02 with total page 847 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutron Cross Sections, Volume 1: Neutron Resonance Parameters and Thermal Cross Sections, Part A represents the fourth edition of what was previously known as BNL-325, Neutron Cross Sections, Volume 1. This three-chapter book provides the extensive list of detailed individual resonance parameters for each isotope. The first chapter deals with the thermal cross sections and average resonance parameters, as well as the physics of thermal and resonance neutrons, with particular emphasis on evaluation methods. This chapter also includes tables of standards of capture cross sections and scattering lengths, and commonly used nuclear physics formulas. The second chapter covers the direct or valence capture and the Brink-Axel treatment of electric dipole radiation. These topics are followed by a discussion on spin-dependent scattering lengths that are of interest to solid state. The third chapter describes the Maxwellian 30-keV capture cross sections that are of importance to studies of nucleosynthesis and age of the universe. This chapter also examines the s- and p-wave average radiative widths and gamma-ray strength functions that are required in capture cross section measurements. This book will appeal to nuclear and astrophysicists.

Download or read book Neutron Capture Cross Sections for Unstable Nuclei in the Mass 90 Region Derived from Proton Capture Measurements. [Strength Functions]. written by and published by . This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental measurements were made of the production cross sections and energy distributions of gamma rays emitted when the stable targets 88Sr, 89Y and 9°Zr are exposed to protons in the energy range 3 to 8 MeV. The data are being analyzed using a recent version of the Uhl statistical model code. One conclusion is that while the gamma-ray strength functions employed reproduce the proton capture cross sections, they do not achieve the same degree of hardness observed in the measured spectra. To do so, their lower energy regions must be modified; such changes, however, do not affect the capture cross sections. 7 references.

This book was released on 2012-12-06 with total page 875 pages. Available in PDF, EPUB and Kindle. Book excerpt: The post World War II era witnessed a tremendous growth in the research carried out in neutron-induced reactions and especially in neutron capture y-ray studies. This growth was stimulated by the availability of neutron sources, such as reactors and accelerators, and by the development of high resolution y-ray and conversion electron detectors. Today the combination of high flux reactors and precise instrumentation has produced spectral data of exceptional quality, as the pages of these proceedings illustrate. The world-wide community of the practioners of the art of cap ture y-ray spectroscopy has met three times in the last decade: the first international symposium on this subject was held at Studsvik, Sweden in 1969, and the second at Petten, The Netherlands in 1974. A smaller meeting, of mostly u. S. and some European parti cipation, was held at Argonne National Laboratory in 1966. A perusal of the proceedings of these meetings shows the striking ad vances in this now mature field of physics over the last dozen years. Each meeting has seen a small but perceptible increase in the number of papers presented and the number of laboratories repre sented. More importantly, each meeting has documented the increasing impact of (n,y) reasearch, not only on other areas of basic physics, but also on commercial and medical applications of this technology. A total of 29 invited papers and 97 contributed papers were presented at this symposium.

Book excerpt: The use of gamma-ray strength function systematics to calculate neutron capture cross sections and capture gamma-ray spectra is discussed. The ratio of the average capture width, GAMMA/sub .gamma./-bar, to the average level spacing, D/sub obs/, both at the neutron separation energy, can be derived from such systematics with much less uncertainty than from separate systematics for values of GAMMA/sub .gamma./-bar and D/sub obs/. In particular, the E1 gamma-ray strength function is defined in terms of the giant dipole resonance (GDR). The GDR line shape is modeled with the usual Lorentzian function and also with a new energy-dependent, Breit-Wigner (EDBW) function. This latter form is further parameterized in terms of two overlapping resonances, even for nuclei where photonuclear measurements do not resolve two peaks. In the mass ranges studied, such modeling is successful for all nuclei away from the N = 50 closed neutron shell. Near the N = 50 shell, a one-peak EDBW appears to be more appropriate. Examples of calculated neutron capture excitation functions and capture gamma-ray spectra using the EDBW form are given for target nuclei in the mass-90 region and also in the Ta-Au mass region. 20 figures.

Available in PDF, EPUB and Kindle. Book excerpt: The International Conference on "Nuclear Structure Study with Neutrons" or ganized in Budapest between 31st July and 5th August. 1972. was the successor of a meeting held seven years ago in Antwerp. The close links between the two conferences were revealed not in name alone but. more importantly. in the choice of subjects discussed. As in Antwerp. the lectures and contributions to the Budapest Conference could be grouped under the following five main headings: nuclear spectroscopy; the optical model; the statistical model and intermediate structures; the mechanism of neutron capture and non-statistical effects; and, finally. miscellaneous special topics. The invited papers on the one hand summarizing recent developments and current thinking in one of the above main topics. and the other surveying the most important results of the contributed papers submitted to the Conference. were presented on the plenary sessions. Most of the contributed papers were read in full on three parallel sessions. This volume contains the complete text of all the lectures delivered in the plenary sessions and abstracts of the contributed papers. The invited talks were presented at the Conference in a rather random order because of technical reasons, it seemed. however, more sensible to change their order according to their subjects and to print them grouped under the above main headings. Further more we divided the Proceedings into two main parts, the first containing only the lectures of summarizing character. the second including the abstracts of the contributions together with the surveying talks.
