  • A. Dynamic Albedo of Neutrons
    Dynamic Albedo of Neutrons (DAN) is a neutron detector instrument on NASA’s Curiosity rover used to measure hydrogen and infer subsurface water content on Mars.
  • B. Bethe–Feynman formula for nuclear explosions
    The Bethe–Feynman formula for nuclear explosions is a theoretical expression developed by Hans Bethe and Richard Feynman that estimates the energy yield and behavior of nuclear detonations based on fundamental physical parameters of the device.
  • C. Meitner–Frisch interpretation of fission
    The Meitner–Frisch interpretation of fission is the 1939 theoretical explanation by Lise Meitner and Otto Frisch that identified nuclear fission as the splitting of heavy atomic nuclei with a corresponding release of enormous energy, laying the groundwork for nuclear physics and atomic energy.
  • D. Journal of Neutron Research
    The Journal of Neutron Research is a scientific journal dedicated to publishing research on the development and application of neutron scattering and related techniques in physics, chemistry, materials science, and related fields.
