  The concept of microstructure of the real space, considered as a mathematical
lattice of cells (the tessel-lattice), and notions of canonical particles and
fields, which are generated by the space, are analyzed. Submicroscopic
mechanics based on this concept is discussed and employed for in-depth study of
the nucleon-nucleon interaction. It is argued that a deformation coat is
developed in the real space around the nucleon (as is the case with any other
canonical particle such as electron, muon, etc.) and that they are the
deformation coats that are responsible for the appearance of nuclear forces.
One more source of nuclear forces is associated with inerton clouds,
excitations of the space tessel-lattice (the excitations are a substructure of
nucleons' matter waves), which accompany moving nucleons as in the case of any
other canonical particles. Two nuclear systems are under consideration: the
deuteron and a weight nucleus. It is shown that a weight nucleus is a cluster
of interacting protons and neutrons. The condition of the cluster stability is
obtained in the framework of the statistical mechanical approach. On the whole,
the paper proposes a radically new approach to a very old unsolved problem, the
origin of the nuclear forces, allowing the understanding mechanism(s) occurring
at low energy nuclear transmutations.
