Nevertheless, working with Fermi’s group in Rome in the 1930s, he took on several behind-the-scenes roles that resulted in important papers in neutron physics. He clarified Fermi’s methodology for calculating neutron slowing down probabilities; using transport theory, he provided a comprehensive general method for calculating the neutron scattering albedo; and with an insight into the way, neutron scattering could yield information about lattice dynamics, he formulated the first theory of inelastic thermal neutrons scattering in crystalline materials. This work and his contributions are not well known today. We discuss its physical essence, its relevance to neutron physics, and its subsequent impact in later work.}, number={1}, journal={EUROPEAN PHYSICAL JOURNAL H}, author={Gould, Christopher R. and Sharapov, Eduard I.}, year={2024}, month={Dec} }

Solar and wind power are established as the low-cost leaders. However, these energy sources are highly variable and electrical power is needed 24/7. Alternative sources must fill the gaps but only a few are both economical and carbon-free or -neutral. This book presents one alternatives: small modular nuclear reactors (SMRs). The authors describe the technology, including its safety and economic aspects, and assess its fit with other carbon-free energy sources, storage solutions, and industrial opportunities. They also explain the challenges with SMRs, including public acceptance. The purpose of the book is to help readers consider these relatively new reactors as part of an appropriate energy mix for the future and, ultimately, to make their own judgements on the merits of the arguments for SMRs.}, publisher={RTI Press}, author={Rao, Vikram and Gould, Chris}, year={2022}, month={Nov} }

All measurements were made using the same reference source, and data sets were of varying length taken over the time period from September 1996 through August 2014. Clear evidence of annual variations was observed in data from four of the detectors. Short time periodograms from the data sets suggest temporal variability of both the amplitude and frequency of these variations. The annual variations in two of the data sets show peak values near the first of February, while surprisingly, the annual variations in the other two are roughly out of phase with the first two. Three of the four detectors exhibited annual variations over approximately the same time period. A joint statistic constructed by combining spectra from these three shows peaks approximating the frequencies of solar r-mode oscillations with νR = 11.74 cpy, m = 1, and l = 3, 5, 6. The fact that similar variations were not present in all detectors covering similar time periods rules out variations in activity as the cause, and points to differing sensitivities to unspecified environmental parameters instead. In addition to seasonal variations, the modulation of environmental parameters by solar processes remains a possible explanation of periodogram features, but without requiring new physics.}, journal={Results in Physics}, publisher={Elsevier BV}, author={Stancil, Daniel D. and Balci Yegen, Sümeyra and Dickey, David A. and Gould, Chris R.}, year={2017}, pages={385–406} }

He enrolled soon after in graduate school at the University of Wisconsin–Madison and began working with Raymond Herb on accelerator construction. In 1944 he went to Los Alamos to join the Manhattan Project, and he found himself in the spring of 1944 as part of a three-person team that measured the critical mass of plutonium-239.As the junior member of the team, Worth worked the overnight shift. In an episode that encapsulates his unfailing optimism that every problem has a solution, he succeeded in hammering out a small dent in one of the plutonium hemispheres after it was dropped on a table. Stationed nine miles away in Alamogordo, New Mexico, Worth witnessed the first nuclear test, and his experiences formed the basis of a memorable presentation he gave hundreds of times to civic and student groups over the following 50 years.Worth returned to Wisconsin in 1948 and, as the first student of Heinz Barschall, completed a dissertation in 1947 on fast-neutron cross sections on aluminum. He then participated in the installation of the research Van de Graaff accelerator at the University of Kansas. Worth worked as a professor of physics at Kansas before moving in 1965 to NC State, where he served as head of the physics department for 10 years. While at NC State, he cofounded the Triangle Universities Nuclear Laboratory and measured nuclear cross sections with secondary neutron beams and with cryogenic polarized targets. After retiring in 1991, he remained as professor emeritus; younger researchers gratefully remember his willingness to help and advise them.Worth offered years of dedicated service to ΣΠΣ and to the Society of Physics Students (SPS). It was during Worth’s tenure as ΣΠΣ president that the honor society merged with the American Institute of Physics (AIP) to form SPS. According to ΣΠΣ’s official history, as the presiding officer, Worth “allowed everyone to have his say and yet kept to the agenda (while he ‘chain-smoked 75 cigars!’).” Needing a two-thirds majority to pass, the articles of agreement between AIP and ΣΠΣ were approved with one vote to spare, 181 out of 270 (see Donald Cunningham and coauthors, Physics Today, September 1968, page 59). The honor society later instituted the Worth Seagondollar Service Award to recognize an exemplary level of commitment and service to SPS and ΣΠΣ. He was the first recipient.Worth’s 23 years as secretary of the Southeast Section of the American Physical Society was the longest tenure of anyone in that position. He steered the section through a period of rapid growth in the physics departments and research facilities in the Southeast and associated growth in participation at section meetings. He received two of the section’s highest awards, one for excellence in teaching physics in the Southeast and the other for service to the section.In retirement, and well into his eighties, Worth remained an active speaker and was invited to give many talks; he felt particularly honored to speak at the ΣΠΣ quadrennial meeting in Albuquerque in 2004. For many years he also set his scientific and managerial skills to planning and executing yard-sale shopping trips. He was known for his early use of GPS to optimize shopping routes. Worth was one of only a few people to ever buy a used, working Mercedes-Benz at a yard sale. He also found many pieces of semi-antique scientific equipment in similar unlikely venues.© 2014 American Institute of Physics.}, number={3}, journal={PHYSICS TODAY}, author={Gould, Chris and Haase, David}, year={2014}, month={Mar}, pages={64–66} }

Modeling of the reactors has become increasingly sophisticated, employing Monte Carlo simulations with realistic geometries and materials that can generate both the thermal and epithermal fractions. The water content and the temperatures of the reactors have been uncertain parameters. We discuss recent work pointing to lower temperatures than earlier assumed. Nuclear cross-sections are input to all Oklo modeling and we discuss a parameter, the 175 Lu ground state cross-section for thermal neutron capture leading to the isomer 176 m  Lu , that warrants further investigation. Studies of the time dependence of dimensionless fundamental constants have been a driver for much of the recent work on Oklo. We critically review neutron resonance energy shifts and their dependence on the fine structure constant α and the ratio Xq = mq/Λ (where mq is the average of the u and d current quark masses and Λ is the mass scale of quantum chromodynamics (QCD)). We suggest a formula for the combined sensitivity to α and Xq that exhibits the dependence on proton number Z and mass number A, potentially allowing quantum electrodynamic (QED) and QCD effects to be disentangled if a broader range of isotopic abundance data becomes available. }, number={04}, journal={International Journal of Modern Physics E}, publisher={World Scientific Pub Co Pte Lt}, author={Davis, E.

Typically such events give rise to a large prompt flash of light followed by a train of delayed photons (‘after‐pulses’). We recently performed an experiment to examine correlations between the amplitude of the initial light pulse and the number of after‐pulses that are produced when a dilute mixture of 3He in l‐4He is irradiated with a neutron beam.

In many cases, these experiments provide important information that is not otherwise available from accelerator-based nuclear physics facilities or high energy accelerators. An energetic research community in the United States is engaged in ''fundamental'' neutron physics. With exciting recent results, the possibility of new and upgraded sources, and a number of new experimental ideas, there is an important opportunity for outstanding science in the next decade. ''Fundamental'' neutron physics experiments are usually intensity limited. Researchers require the highest flux neutron sources available, which are either high-flux reactors (continuous sources) or spallation neutron sources (pulsed sources). The primary mission of these major facilities is neutron scattering for materials science research.

The depolarization was dependent on the relative orientation of the neutron polarization and the holmium c crystalline axis. The effect was explained in terms of neutron precession in an array of highly correlated domains magnetized in the c axis direction. The results show the high degree of correlation of magnetic domains in the single crystal and demonstrate the usefulness of epithermal neutrons in measuring magnetic properties of thick crystals.

The system runs under VMS and uses commercially available hardware for the bulk of the interface. The code is written almost exclusively in Fortran and uses many software components and ideas from other laboratories. All users share common versions of applications tasks, reducing problems associated with program proliferation and documentation.All event sorting is performed by the event analysis language EVAL. Singles data rates of about 70 KHz use about a third of the available CPU time. This has little or no impact on the response time for the other off-line users. Taking over work from an other facility is a convenient and fast way of implementing a data acquisition system when the computer and interface are identical. This was the case for us with the MBD software and the graphics software. If the hardware configuration is different, however, implementation may be difficult unless one of the programmers is very familiar with the system being installed. The key parts of our system, EVAL and the Z-like data structures, did require modification. They were developed during a three month visit by one of the authors (RVP). Once these foundations were laid, the work of writing the full system could be spread around a number of people.

Four 7.6 cm × 10.2 cm NaI(Tl) crystals are simultaneously used to detect coincident γ-rays at angles between 60° and 160°. Details of precautions taken to reduce γ-ray and particle backgrounds are given. Data are accumulated in three parameter mode using a computer-analyzer system.}, number={3}, journal={Nuclear Instruments and Methods}, publisher={Elsevier BV}, author={Zurmühle, R.W. and Hinrichsen, P.F. and Fou, C.M. and Gould, C.R. and Anastassiou, G.P.}, year={1969}, month={Jun}, pages={311–316} }
