2. Neutron scattering - Wikipedia

   en.wikipedia.org/wiki/Neutron_scattering

   Today, most neutron scattering experiments are performed by research scientists who apply for beamtime at neutron sources through a formal proposal procedure. Because of the low count rates involved in neutron scattering experiments, relatively long periods of beam time (on the order of days) are usually required for usable data sets.

3. Neutron spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Neutron_spectroscopy

   Inelastic neutron scattering observes the change in the energy and wavevector of the neutron as it scatters from a sample. [1] This can be used to probe a wide variety of different physical phenomena such as the motions of atoms (diffusional or hopping), the rotational modes of molecules, sound modes and molecular vibrations , recoil in quantum ...

4. Structure factor - Wikipedia

   en.wikipedia.org/wiki/Structure_factor

   The structure factor is a critical tool in the interpretation of scattering patterns (interference patterns) obtained in X-ray, electron and neutron diffraction experiments. Confusingly, there are two different mathematical expressions in use, both called 'structure factor'.

5. Neutron diffraction - Wikipedia

   en.wikipedia.org/wiki/Neutron_diffraction

   Neutron diffraction or elastic neutron scattering is the application of neutron scattering to the determination of the atomic and/or magnetic structure of a material. A sample to be examined is placed in a beam of thermal or cold neutrons to obtain a diffraction pattern that provides information of the structure of the material.

6. Debye–Waller factor - Wikipedia

   en.wikipedia.org/wiki/Debye–Waller_factor

   Scattering experiments are a common method for learning about crystals.Such experiments typically involve a probe (e.g. X-rays or neutrons) and a crystalline solid.A well-characterized probe propagating towards the crystal may interact and scatter away in a particular manner.

7. Small-angle neutron scattering - Wikipedia

   en.wikipedia.org/wiki/Small-angle_neutron_scattering

   In neutron scattering, neutrons interact with nuclei and the interaction depends on the isotope; some light elements like deuterium show similar scattering cross section as heavy elements like Pb. In zero order dynamical theory of diffraction the refractive index is directly related to the scattering length density and is a measure of the ...

8. List of scattering experiments - Wikipedia

   en.wikipedia.org/wiki/List_of_scattering_experiments

   Davisson–Germer experiment; Gold foil experiments, performed by Geiger and Marsden for Rutherford which discovered the atomic nucleus; Elucidation of the structure of DNA by X-ray crystallography; Discovery of the antiproton at the Bevatron; Discovery of W and Z bosons at CERN; Discovery of the Higgs boson at the Large Hadron Collider; MINERνA

9. Shape of the atomic nucleus - Wikipedia

   en.wikipedia.org/wiki/Shape_of_the_atomic_nucleus

   The largest stable nuclide, lead-208, has an RMS charge radius of 5.5012 fm, and the largest unstable nuclide americium-243 has an experimental RMS charge radius of 5.9048 fm. [2] The main source of nuclear radius values derives from elastic scattering experiments (electron and muon), but nuclear radii data also come from experiments on ...
