  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 ...

    Second, it comprises fundamental aspects of both quantum tunnelling as well as the coupling of (quasi)bound quantum states with the continuum in mesoscopic systems such as the atomic nucleus. Theoretical approaches can start either from bound-state nuclear shell-model theory or from resonance scattering.

  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. Angular momentum coupling - Wikipedia

    en.wikipedia.org/wiki/Angular_momentum_coupling

    All nuclear levels whose ℓ value (orbital angular momentum) is greater than zero are thus split in the shell model to create states designated by ℓ + s and ℓ − s. Due to the nature of the shell model , which assumes an average potential rather than a central Coulombic potential, the nucleons that go into the ℓ + s and ℓ − s ...

  6. Woods–Saxon potential - Wikipedia

    en.wikipedia.org/wiki/Woods–Saxon_potential

    Woods–Saxon potential for A = 50, relative to V 0 with a = 0.5 fm and =. The Woods–Saxon potential is a mean field potential for the nucleons (protons and neutrons) inside the atomic nucleus, which is used to describe approximately the forces applied on each nucleon, in the nuclear shell model for the structure of the nucleus.

  7. 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.

  8. Nuclear physics - Wikipedia

    Superimposed on this classical picture, however, are quantum-mechanical effects, which can be described using the nuclear shell model, developed in large part by Maria Goeppert Mayer [28] and J. Hans D. Jensen. [29] Nuclei with certain "magic" numbers of neutrons and protons are particularly stable, because their shells are filled.

  9. Atomic nucleus - Wikipedia

    en.wikipedia.org/wiki/Atomic_nucleus

    A model of an atomic nucleus showing it as a compact bundle of protons (red) and neutrons (blue), the two types of nucleons.In this diagram, protons and neutrons look like little balls stuck together, but an actual nucleus (as understood by modern nuclear physics) cannot be explained like this, but only by using quantum mechanics.
