ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

A study of the average s- and þ-wave resonance parameters of 115In and 127I has been carried out by activation of samples in a 10B filtered beam of epithermal neutrons from a reactor. Neutron strength functions were obtained that are comparable to recent values obtained by total-cross-section studies but somewhat lower than earlier capture measurements. The s- and þ-wave neutron strength functions for 115In were found to be 0.09 ± 0.03 × 10−4 and 3.9 ± 1.4 × 10−4, respectively, and for 127I, the corresponding values were found to be 0.42 × 10−4 and 0.83 ± 0.20 × 10−4. The average energy-dependent neutron cross sections from 1 to 100 keV were computed for both isotopes from the experimentally determined resonance parameters.
