  2. Nuclear shell model - Wikipedia

    en.wikipedia.org/wiki/Nuclear_shell_model

    A model derived from the nuclear shell model is the alpha particle model developed by Henry Margenau, Edward Teller, J. K. Pering, T. H. Skyrme, also sometimes called the Skyrme model. [ 8 ] [ 9 ] Note, however, that the Skyrme model is usually taken to be a model of the nucleon itself, as a "cloud" of mesons (pions), rather than as a model of ...

  3. Magic number (physics) - Wikipedia

    en.wikipedia.org/wiki/Magic_number_(physics)

    In the shell model for the nucleus, magic numbers are the numbers of nucleons at which a shell is filled. For instance, the magic number 8 occurs when the 1s 1/2 , 1p 3/2 , 1p 1/2 energy levels are filled, as there is a large energy gap between the 1p 1/2 and the next highest 1d 5/2 energy levels.

  4. Nilsson model - Wikipedia

    en.wikipedia.org/wiki/Nilsson_model

    The Nilsson model is a nuclear shell model treating the atomic nucleus as a deformed sphere. In 1953, the first experimental examples were found of rotational bands in nuclei, with their energy levels following the same J(J+1) pattern of energies as in rotating molecules.

  5. Nuclear structure - Wikipedia

    en.wikipedia.org/wiki/Nuclear_structure

    A nucleus with full shells is exceptionally stable, as will be explained. As with electrons in the electron shell model, protons in the outermost shell are relatively loosely bound to the nucleus if there are only few protons in that shell, because they are farthest from the center of the nucleus. Therefore, nuclei which have a full outer ...

  6. Valley of stability - Wikipedia

    en.wikipedia.org/wiki/Valley_of_stability

    The hypothesis for the island of stability is based upon the nuclear shell model, which implies that the atomic nucleus is built up in "shells" in a manner similar to the structure of the much larger electron shells in atoms. In both cases, shells are just groups of quantum energy levels that are relatively close to each other. Energy levels ...

  7. Nuclear physics - Wikipedia

    en.wikipedia.org/wiki/Nuclear_physics

    The study of the strong and weak nuclear forces (the latter explained by Enrico Fermi via Fermi's interaction in 1934) led physicists to collide nuclei and electrons at ever higher energies. This research became the science of particle physics , the crown jewel of which is the standard model of particle physics , which describes the strong ...

    Nuclear fusion, after all, is the same energy that powers the sun and every other star in the universe. Being able to harness and replicate it means that humankind could one day tap an almost ...

  9. Shell model - Wikipedia

    en.wikipedia.org/wiki/Shell_model

    Shell model can mean: Nuclear shell model, how protons and neutrons are arranged in an atom nucleus; Electron shell, how electrons are arranged in an atom or molecule;
