This book was released on 1965 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: High resolution measurements of the gamma ray spectra from thermal and resonance neutron capture in 117Sn, 118Sn and 120Sn have been made with a lithium-drifted germanium detector. A beam of pure thermal neutrons was obtained by double reflection from inconel mirrors of a reactor beam from the Oak Ridge Research Reactor. A cadmium filtered reactor beam served as the source of resonance neutrons. Earlier measurements of the gamma rays from the isotopes of tin with a NaI spectrometer had demonstrated the value of using both thermal and resonance energy neutrons and the need for higher resolution of the gamma rays. The lithium-drifted germanium crystal was 2.6 cm2 in area by 7 mm thick and was furnished by R.J. Fox, ORNL. For high energy gamma rays (> H"2000 keV) the pair production process with the subsequent escape of both annihilation quanta is the predominant process. Above 4000 keV the resolution was 10-15 keV for runs of several days duration and the energies of the lines may be measured to ± 10 keV absolute and ± 5 keV relative. For low energy gamma rays (

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.

Download or read book High Energy Resolution Measurement of the /sup 238/U Neutron Capture Yield from 1 KeV to 100 KeV. written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this work is the precise determination of the /sup 238/U neutron capture yield (i.e., the probability of neutron absorption) as a function of neutron energy with the highest available neutron energy resolution. The motivation for this undertaking arises from the central role played by the /sup 238/U neutron capture process in the calculation of the neutron balance of both thermal reactors and fast breeder reactors. The present measurement was performed using the Oak Ridge Electron Linear Accelerator (ORELA) facility. The pulsed beam of neutrons from the ORELA facility is collimated on a sample of /sup 238/U. The neutron capture rate in the sample is measured, as a function of neutron time-of-flight (TOF), by detecting the gamma rays from the /sup 238/U(n, .gamma.)/sup 239/U reaction with a large gamma-ray detector surrounding the /sup 238/U sample. At each energy, the capture yield is proportional to the observed capture rate divided by the measured intensity of the neutron beam. The constant of proportionality (the normalization constant) is obtained as the ratio of theoretical to experimentally measured areas under small /sup 238/U resonances where the resonance parameters have been determined from high resolution /sup 238/U transmission measurements. The cross section for the reaction /sup 238/U(n, .gamma.)/sup 239/U can be derived from the measured capture yield if one applies appropriate corrections for multiple scattering and resonance self-shielding. The present work will allow the extension of the resolved resonance region in /sup 238/U from its current limit of 4 keV up to 20 keV. In addition, some 200 /sup 238/U neutron resonances in the energy range from 250 eV to 10 keV have been observed which had not been detected in previous measurements. These results are relevant for both reactor design and for the understanding of the structure of the (/sup 238/U + n) compound nucleus. 33 refs., 20 figs., 9 tabs.
