Book Description
A neutron-gamma ray spectrometer developed at Texas Nuclear Corporation is described. The spectrometer employs pulse shape discrimination in an organic scintillator detector to selectively detect neutrons or gamma rays in a mixed field by a method not utilizing space charge limiting. Selective detection may be obtained for neutrons of energy higher than 0.7 MeV and for gamma rays above 0.25 MeV. Spectral information is usable to 15 MeV for neutrons and to 4 MeV for gamma rays. Detection efficiencies range from about 6% to 30%. Typical spectra, data analysis procedure, and operating characteristics of the spectrometer are presented.

Book Description
The instrumentation package of a spectrometer system for neutrons and gamma rays is discussed in detail. The pulse signals produced in stilbene crystal by neutrons and gamma rays are stored simultaneously in different memory subgroups of a multichannel analyzer by using pulse shape discrimination techniques. Neutrons in the energy range from 0.5 MeV to 20 MeV and gamma rays in the energy range from 0.15 MeV to 11 MeV are analyzed with a discrimination ratio exceeding 1000:1. The lower energy discrimination limit of the system is 22 keV electron energy which corresponds to 270 keV neutron energy and 90 keV gamma ray energy. (Author).

Book Description
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.
