Book excerpt: Cross sections for radiative neutron capture on unstable nuclei at low energies are difficult to calculate with high precision, and can be impossible to measure directly. It is therefore important to explore alternative methods. The prospects of one such method, the Surrogate Nuclear Reaction Technique, is currently being investigated at Lawrence Livermore National Laboratory. The purpose of this paper is to outline the strategy for combining the results from a surrogate experiment with theoretical calculations in order to extract the desired cross section.

Available in PDF, EPUB and Kindle. Book excerpt: Cross sections for compound-nuclear reactions play an important role in models of astrophysical environments and simulations of the nuclear fuel cycle. Providing reliable cross section data remains a formidable task, and direct measurements have to be complemented by theoretical predictions and indirect methods. The surrogate nuclear reactions method provides an indirect approach for determining cross sections for reactions on unstable isotopes, which are difficult or impossible to measure otherwise. Current implementations of the method provide useful cross sections for (n, f) reactions, but need to be improved upon for applications to capture reactions.

This book was released on 2018 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition to \textsuperscript{235,238}U and \textsuperscriptPu, \textsuperscriptPu is considered a major actinide in regards to nuclear fuel and systems. Despite contributing up to $\sim$10$\%$ of energy generated in nuclear reactors towards the end of a cycle, nuclear data for this isotope is limited. Due to its 14 year half-life, target manufacturing for this isotope is difficult, and as a result the (n,xn) cross section and fission neutron multiplicity as a function of incident neutron energy for $^$Pu does not exist in the published literature. Using the surrogate ratio method, experimental difficulties associated with target manufacturing can be circumvented in measuring n + $^$Pu reactions by using inelastic scattering of $\alpha$ particles incident on $^$Pu to create the same compound nucleus. The NeutronSTARS detection array in Cave 4 of the Texas A$\&$M Cyclotron was commissioned specifically for experiments of this nature. The target chamber consists of three large area silicon detectors: two serve as a silicon telescope to determine the energy of the scattered alpha particle, and one fission detector to gate on fission events by detecting fission fragments. A segmented cylindrical array consisting of ~2.2 tons of gadolinium doped liquid scintillator is used to detect emitted neutrons. By relating the detected recoiled alpha energy to an equivalent neutron energy, detecting fission fragments to separate neutron evaporation events from fission, and detecting emitted neutrons in close time coincidence; an attempt to measure the (n,xn) cross section and prompt fission multiplicity for $^$Pu was made. The prompt fission neutron multiplicity was fit to a skewed Gaussian distribution, while the average neutron multiplicity was recorded. Due to the large contribution of oxygen and carbon in the target, relatively low neutron detection efficiency, and inadequate background rejection for non-fission events; the (n,xn) cross section measurement was difficult to extract.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook is a comprehensive, systematic source of modern nuclear physics. It aims to summarize experimental and theoretical discoveries and an understanding of unstable nuclei and their exotic structures, which were opened up by the development of radioactive ion (RI) beam in the late 1980s. The handbook comprises three major parts. In the first part, the experiments and measured facts are well organized and reviewed. The second part summarizes recognized theories to explain the experimental facts introduced in the first part. Reflecting recent synergistic progress involving both experiment and theory, the chapters both parts are mutually related. The last part focuses on cosmo-nuclear physics—one of the mainstream subjects in modern nuclear physics. Those comprehensive topics are presented concisely. Supported by introductory reviews, all chapters are designed to present their topics in a manner accessible to readers at the graduate level. The book therefore serves as a valuable source for beginners as well, helping them to learn modern nuclear physics.

Book excerpt: This book describes the Proceedings of the International Conference on Nuclear Data for Science and Technology held at Jillich in May 1991. The conference was in a series of application oriented nuclear data conferences organized in the past under the auspices of the Nuclear Energy Agency-Nuclear Data Committee (NEANDC) and with the support of the Nuclear Energy Agency-Committee on Reactor Physics (NEACRP). It was the fIrst international conference on nuclear data held in Germany, with the scientific responsibility entrusted to the Institute of Nuclear Chemistry of the Research Centre Jillich. The scientific programme was established by the International Programme Committee in consultation with the International Advisers, and the NEA and IAEA cooperated in the organization. A total of 328 persons from 37 countries and fIve international organizations participated. The scope of these Proceedings extends to a wide range of interdisciplinary topics dealing with measu rement, calculation, evaluation and application of nuclear data, with a major emphasis on numerical data. Both energy and non-energy related applications are considered and due attention is given to some fundamental aspects relevant to the understanding of nuclear data.

Book excerpt: The principal goals of the study were to articulate the scientific rationale and objectives of the field and then to take a long-term strategic view of U.S. nuclear science in the global context for setting future directions for the field. Nuclear Physics: Exploring the Heart of Matter provides a long-term assessment of an outlook for nuclear physics. The first phase of the report articulates the scientific rationale and objectives of the field, while the second phase provides a global context for the field and its long-term priorities and proposes a framework for progress through 2020 and beyond. In the second phase of the study, also developing a framework for progress through 2020 and beyond, the committee carefully considered the balance between universities and government facilities in terms of research and workforce development and the role of international collaborations in leveraging future investments. Nuclear physics today is a diverse field, encompassing research that spans dimensions from a tiny fraction of the volume of the individual particles (neutrons and protons) in the atomic nucleus to the enormous scales of astrophysical objects in the cosmos. Nuclear Physics: Exploring the Heart of Matter explains the research objectives, which include the desire not only to better understand the nature of matter interacting at the nuclear level, but also to describe the state of the universe that existed at the big bang. This report explains how the universe can now be studied in the most advanced colliding-beam accelerators, where strong forces are the dominant interactions, as well as the nature of neutrinos.
