Geiger–Marsden experiment

Target entity: Geiger–Marsden experiment
Context triple: [Hans Geiger, knownFor, Geiger–Marsden experiment]

• A. 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.
• B. 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.
• C. 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.
• D. 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.
• E. Cockcroft–Walton experiment
  The Cockcroft–Walton experiment was a pioneering 1932 nuclear physics experiment that achieved the first artificial disintegration of atomic nuclei using accelerated protons, confirming Einstein’s mass–energy equivalence.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Geiger–Marsden experiment
Target entity description: 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.
