Target entity: Geiger–Marsden experiment
Context triple: [Ernest Marsden, knownFor, Geiger–Marsden experiment]
  • A. Geiger–Marsden experiment chosen
    The Geiger–Marsden experiment, also known as the gold foil experiment, was a landmark early 20th-century physics experiment that revealed the existence of a small, dense atomic nucleus and led to the development of the Rutherford model of the atom.
  • B. Davisson–Germer experiment
    The Davisson–Germer experiment was a landmark 1927 physics experiment that demonstrated the wave nature of electrons through diffraction from a nickel crystal, providing key evidence for quantum mechanics and wave–particle duality.
  • C. Franck–Hertz experiment
    The Franck–Hertz experiment is a landmark early-20th-century physics experiment that provided direct evidence for the quantization of atomic energy levels, supporting the Bohr model of the atom.
  • D. Trouton–Noble experiment
    The Trouton–Noble experiment was an early 20th-century test of the luminiferous aether that searched for a torque on a charged capacitor in motion and, by finding no such effect, provided support for the emerging theory of special relativity.
  • E. Meitner–Hahn experiments
    The Meitner–Hahn experiments were pioneering nuclear physics investigations in the 1930s that led to the discovery and explanation of nuclear fission in uranium.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
