  2. Nuclear force - Wikipedia

    en.wikipedia.org/wiki/Nuclear_force

    Energy is released when a heavy nucleus breaks apart into two or more lighter nuclei. This energy is the internucleon potential energy that is released when the nuclear force no longer holds the charged nuclear fragments together. [3] [4] A quantitative description of the nuclear force relies on equations that are partly empirical. These ...

  3. Potential energy - Wikipedia

    en.wikipedia.org/wiki/Potential_energy

    There are various types of potential energy, each associated with a particular type of force. For example, the work of an elastic force is called elastic potential energy; work of the gravitational force is called gravitational potential energy; work of the Coulomb force is called electric potential energy; work of the strong nuclear force or weak nuclear force acting on the baryon charge is ...

  4. Nuclear reaction - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reaction

    Nuclear physics. In nuclear physics and nuclear chemistry, a nuclear reaction is a process in which two nuclei, or a nucleus and an external subatomic particle, collide to produce one or more new nuclides. Thus, a nuclear reaction must cause a transformation of at least one nuclide to another. If a nucleus interacts with another nucleus or ...

  5. Rutherford scattering experiments - Wikipedia

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

    The true radius of the nucleus is not recovered in these experiments because the alphas do not have enough energy to penetrate to more than 27 fm of the nuclear center, as noted, when the actual radius of gold is 7.3 fm. Figure 1. Potential energy diagram for Rutherford's atom model illustrating concentration in the nucleus.

  6. Nuclear shell model - Wikipedia

    en.wikipedia.org/wiki/Nuclear_shell_model

    In nuclear physics, atomic physics, and nuclear chemistry, the nuclear shell model utilizes the Pauli exclusion principle to model the structure of atomic nuclei in terms of energy levels. [ 1 ] The first shell model was proposed by Dmitri Ivanenko (together with E. Gapon) in 1932. The model was developed in 1949 following independent work by ...

  7. Nuclear energy - Wikipedia

    en.wikipedia.org/wiki/Nuclear_energy

    Nuclear power, the use of sustained nuclear fission or nuclear fusion to generate heat and electricity. Nuclear binding energy, the energy needed to fuse or split a nucleus of an atom. Nuclear potential energy, the potential energy of the particles inside an atomic nucleus. Nuclear Energy (sculpture), a bronze sculpture by Henry Moore in the ...

  8. Nuclear structure - Wikipedia

    en.wikipedia.org/wiki/Nuclear_structure

    The liquid drop model is one of the first models of nuclear structure, proposed by Carl Friedrich von Weizsäcker in 1935. [5] It describes the nucleus as a semiclassical fluid made up of neutrons and protons, with an internal repulsive electrostatic force proportional to the number of protons. The quantum mechanical nature of these particles ...

  9. Energy - Wikipedia

    en.wikipedia.org/wiki/Energy

    Nuclear: potential energy that binds nucleons to form the atomic nucleus (and nuclear reactions) Chromodynamic: potential energy that binds quarks to form hadrons: Elastic: potential energy due to the deformation of a material (or its container) exhibiting a restorative force as it returns to its original shape Mechanical wave
