  2. Nuclear physics - Wikipedia

    en.wikipedia.org/wiki/Nuclear_physics

    Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics , which studies the atom as a whole, including its electrons .

  3. Nuclear force - Wikipedia

    en.wikipedia.org/wiki/Nuclear_force

    The nuclear force has been at the heart of nuclear physics ever since the field was born in 1932 with the discovery of the neutron by James Chadwick. The traditional goal of nuclear physics is to understand the properties of atomic nuclei in terms of the "bare" interaction between pairs of nucleons, or nucleon–nucleon forces (NN forces).

  4. Rutherford model - Wikipedia

    en.wikipedia.org/wiki/Rutherford_model

    [5]: 145 Perrin later credited Rutherford with the discovery of the nuclear model. [6] A somewhat similar model proposed by Hantaro Nagaoka in 1904 used Saturn's rings as an analog. [2]: 37 The rings consisted of a large number of particles that repelled each other but were attracted to a large central charge. This charge was calculated to be ...

  5. Nuclear magnetic moment - Wikipedia

    en.wikipedia.org/wiki/Nuclear_magnetic_moment

    According to the shell model, protons or neutrons tend to form pairs of opposite total angular momentum.Therefore, the magnetic moment of a nucleus with even numbers of each protons and neutrons is zero, while that of a nucleus with an odd number of protons and even number of neutrons (or vice versa) will have to be that of the remaining unpaired nucleon.

  6. List of equations in nuclear and particle physics - Wikipedia

    en.wikipedia.org/wiki/List_of_equations_in...

    The following apply for the nuclear reaction: a + b ↔ R → c in the centre of mass frame , where a and b are the initial species about to collide, c is the final species, and R is the resonant state .

  7. Nuclear reaction - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reaction

    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.

  8. Subatomic particle - Wikipedia

    en.wikipedia.org/wiki/Subatomic_particle

    Particle physics and nuclear physics study these particles and how they interact. [3] Most force-carrying particles like photons or gluons are called bosons and, although they have quanta of energy, do not have rest mass or discrete diameters (other than pure energy wavelength) and are unlike the former particles that have rest mass and cannot ...

  9. Neutron radiation - Wikipedia

    en.wikipedia.org/wiki/Neutron_radiation

    Neutron radiation is a form of ionizing radiation that presents as free neutrons.Typical phenomena are nuclear fission or nuclear fusion causing the release of free neutrons, which then react with nuclei of other atoms to form new nuclides—which, in turn, may trigger further neutron radiation.
