Nuclear forces and quantum chromodynamics

Nuclear forces in the lightest atomic nuclei (D, T, 3He, 4He) have been considered on the basis of a simplified model of quantum chromodynamics. They are considered to mainly arise at the expense of exchange of colour quarks between nucleons at small distances. At large distances the mechanism of π meson exchange remains valid. The relation obtained between binding energies of the lightest nuclei does not contradict experimental data and testifies that two- and three-particle exchange forces introduced in such a way are realistic
