  • Comparison between the Nuclear Force and the Coulomb Force.
'''a''' - residual strong force (nuclear force), rapidly decreases to insignificance at distances beyond about 2.5 fm,
'''b''' - at distances less than ~ 0.7 fm between nucleons centers the nuclear force becomes repulsive,
'''c''' - coulomb repulsion force between two protons (over 3 fm force becomes the main),
'''d''' - equilibrium position for proton - proton, 
'''r''' - radius of a nucleon (a cloud composed of three quarks).
Note: 1 fm = 1E-15 m.

  • The same diagram as that above with the individual [[quark]] constituents shown, to illustrate how the ''fundamental'' [[strong interaction]] gives rise to the '''nuclear force'''. Straight lines are quarks, while multi-colored loops are [[gluon]]s (the carriers of the fundamental force).

  • S]] angular momentum state. The attractive (negative) force has a maximum at a distance of about 1 fm with a force of about 25,000 N. Particles much closer than a distance of 0.8 fm experience a large repulsive (positive) force. Particles separated by a distance greater than 1 fm are still attracted (Yukawa potential), but the force falls as an exponential function of distance.
  • Corresponding potential energy (in units of MeV) of two nucleons as a function of distance as computed from the Reid potential. The potential well has a minimum at a distance of about 0.8 fm. With this potential nucleons can become bound with a negative "binding energy".

The nuclear force (or nucleonnucleon interaction, residual strong force, or, historically, strong nuclear force) is a force that acts between the protons and neutrons of atoms. Neutrons and protons, both nucleons, are affected by the nuclear force almost identically.

Nucleon pair breaking
Nucleon pair breaking in fission has been an important topic in nuclear physics for decades. "Nucleon pair" refers to nucleon pairing effects which strongly influence the nuclear properties of a nuclide.

Ford Nucleon

The Ford Nucleon is a concept car developed by Ford in 1957, designed as a future nuclear-powered car—one of a handful of such designs during the 1950s and 1960s. The concept was only demonstrated as a scale model. The design did not include an internal-combustion engine; rather, the vehicle was to be powered by a small nuclear reactor in the rear of the vehicle, based on the assumption that this would one day be possible by reducing sizes. The car was to use a steam engine powered by uranium fission, similar to those found in nuclear submarines.

The mock-up of the car can be viewed at the Henry Ford Museum in Dearborn, Michigan.
