How do we determine the magnitude of the nuclear force acting on the nucleus of an atom?
Astronuc said:Here's one explanation -
Why is the range of the strong force so small? Production and destruction of the messenger mesons violates the law of conservation of mass & energy! However, if the messenger particle has a very short lifetime, and so exists only within a very small space, the particle can exist within the limitations set by the uncertainty principle. Particles like this are called virtual particles.

Well put.humanino said:Q : "how is the strength of the interaction determined ?"
A : "Through very efficient models"
The nuclear force, also known as the strong force, is one of the four fundamental forces of nature. It is responsible for holding together the protons and neutrons in an atom's nucleus, overcoming the repulsive forces between positively charged protons.
The nuclear force is a short-range force that acts between particles called nucleons (protons and neutrons). It is mediated by particles called gluons, which carry the force between nucleons. The nuclear force is very strong, but it only acts over very short distances, typically within the size of an atomic nucleus.
The nuclear force is crucial for the stability of atoms and the formation of elements. Without the nuclear force, the repulsive forces between protons would cause the nucleus to break apart, preventing the existence of atoms. The nuclear force also plays a role in nuclear reactions, such as fusion and fission, which release large amounts of energy.
The nuclear force is not directly measurable, but its effects can be observed and measured through experiments, such as scattering experiments using high-energy particles. The strength of the nuclear force is also determined by studying the binding energy of nuclei, which is the energy required to break apart the nucleus into its individual nucleons.
The nuclear force is a fundamental force and cannot be controlled or manipulated in the same way as other forces, such as gravity or electromagnetism. However, it can be harnessed through nuclear technology, such as in nuclear power plants and nuclear weapons. Scientists continue to study the nuclear force in hopes of gaining a deeper understanding of its properties and potential applications.
