The Unified Theory has established that contrary to the definition accepted in modern theoretical physics, strong nuclear interaction is not an attraction (Unified Theory of Nature and Why the nuclear interaction is the strong? see). Secondly, it was found that the structure of the proton and neutron is much simpler than is accepted in modern physics. It has been established that both the proton and the neutron are micro-vortexes of the ether (Substance and its physical properties and What is a neutron star? see). Thirdly, it was found that the real mechanism of nuclear interaction, in contrast to the accepted one, is also very simple.

It has been established that protons and neutrons, being torus ether microvortexes, mutually catch on each other when they collide (Why deuterium is stable? see). For the formation of the nucleus of an atom and its life, no additional particles (quarks) are needed. This is confirmed by the well-known numerous nuclear experiences also. Quarks did not fly out of hadrons under any nuclear reactions. The Unified Theory already confirmed by its many successful applications (Universality of the Theory see), allows us to state, that quarks will never be detected, since the connection of nucleons is determined not by quarks, but by the detected microvortex structure of nucleons.

The Unified Theory also reveals the reason for the manifestation of strong nuclear interactions at very short distances. The reason is the small size of the mutually linked torus microvortices — nucleons (see above "What is a neutron star?”). So, in order to break two linked ether micro-vortexes (proton and neutron) in deuterium, it is necessary to stretch these two non-mutually contacting two links to their mutual internal contact. Obviously, this movement is equal to a distance close to the size of the internal aperture of the torus microvortex — the nucleon (see above “Why deuterium is stable?”).

The indicated short-range zone of nuclear force will have the strictly defined value. This is due to the strict determination of the size of the nucleon - the ether microvortex (The steady structures of material Space see). Then from the Unified Theory it follows that for smaller nuclei the zone of manifestation of this short action will be slightly larger than the size of a small nucleus - a small cluster of linked nucleons, that is, several times more of proton. For larger nuclei, this zone will be close to the size of the larger nucleus, since the engagement occurs on the surface of the cluster — an adhered compact set of microvortexes.

According to the Unified Theory, at greater distances, the proton and neutron are indifferent to each other. This follows from the fact that the nucleon – microvortex is a dense compact formation of ether ("What is a neutron star?”see above), which due to its properties, manifests itself only in direct contact. When a proton is superimposed on a neutron (colliding at a relatively low speed), they are repelled in accordance with the Unified Theory. This follows from the fact that each ether microvortex is an elastic stable structure that prevents its deformation ("Substance and its physical properties" see above and The 1st law of existence of Universe see).

How beautiful you are, Unified Theory!
