  2. Rutherford scattering experiments - Wikipedia

    en.wikipedia.org/wiki/Rutherford_scattering...

    Rutherford scattering or Coulomb scattering is the elastic scattering of charged particles by the Coulomb interaction. The paper also initiated the development of the planetary Rutherford model of the atom and eventually the Bohr model. Rutherford scattering is now exploited by the materials science community in an analytical technique called ...

  3. Rutherford backscattering spectrometry - Wikipedia

    en.wikipedia.org/wiki/Rutherford_backscattering...

    Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science.Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.

  4. Ernest Rutherford - Wikipedia

    en.wikipedia.org/wiki/Ernest_Rutherford

    Succeeded by. Lawrence Bragg. Signature. Ernest Rutherford, 1st Baron Rutherford of Nelson, OM , FRS , HonFRSE [ 7 ] (30 August 1871 – 19 October 1937), was a New Zealand physicist who was a pioneering researcher in both atomic and nuclear physics. He has been described as "the father of nuclear physics", [ 8 ] and "the greatest ...

  5. Scattering - Wikipedia

    en.wikipedia.org/wiki/Scattering

    Rayleigh scattering is a process in which electromagnetic radiation (including light) is scattered by a small spherical volume of variant refractive indexes, such as a particle, bubble, droplet, or even a density fluctuation. This effect was first modeled successfully by Lord Rayleigh, from whom it gets its name.

  6. Rutherford model - Wikipedia

    en.wikipedia.org/wiki/Rutherford_model

    The Rutherford model was devised by Ernest Rutherford to describe an atom. Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson 's plum pudding model of the atom was incorrect. Rutherford's new model [1] for the atom, based on the experimental results, contained new ...

  7. Nuclear reaction analysis - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reaction_analysis

    Rutherford backscattering (RBS) reactions are elastic (Q = 0), and the interaction (scattering) cross-section σ given by the famous formula derived by Lord Rutherford in 1911. But non -Rutherford cross-sections (so-called EBS , elastic backscattering spectrometry ) can also be resonant: for example, the 16 O(α,α) 16 O reaction has a strong ...

  8. Plum pudding model - Wikipedia

    en.wikipedia.org/wiki/Plum_pudding_model

    The scattering model predictions were not considered definitive evidence against Thomson's plum pudding model. Thomson and Rutherford had pioneered scattering as a technique to probe atoms, its reliability and value were unproven. Before Rutherford's paper the alpha particle was considered an atom, not a compact mass.

  9. Backscatter - Wikipedia

    en.wikipedia.org/wiki/Backscatter

    Backscatter. In physics, backscatter (or backscattering) is the reflection of waves, particles, or signals back to the direction from which they came. It is usually a diffuse reflection due to scattering, as opposed to specular reflection as from a mirror, although specular backscattering can occur at normal incidence with a surface.
