- Аннотация: The report discusses possible mechanisms for creation of hyperheavy nuclei by electron-nuclear collapse, and neutron matter by ultra-cold neutron condensation (UCNs). The principal possibility of creation such objects was previously justified by A. B. Migdal, who suggested that the known set of proton-neutron nuclei with mass numbers from 0 up to 300 and a minimum energy of about 8 MeV/nucleon at A≈60 (in the iron region) corresponds to the first region, behind which (starting from about the charge Z≈1700) is another region describing the possible state of nuclear matter stabilized by pion condensate. In this area, the minimum energy corresponds to 20 MeV/nucleon at A≈200000. The report shows that a neutron substance can be implemented under certain conditions, and its systematization can be implemented as an addition to the Periodic table. When solving such problems, it becomes quite real to study not only physical, but also chemical, and possibly engineering and technical properties. Neutron matter is already stable at the micro level by the Tamm interaction, the Hund beta equilibrium, and it can be quite stable not only at the macro level (neutron stars) due to the gravitational interaction, as a priori it was assumed earlier, but also on the scale of "ordinary" matter. The analysis shows that the neutro-nization process is possible not only under critical gravitational interaction, but also through other mechanisms (supercritical increase in the atomic number of elements through electron-nuclear collapse and condensation of ultracold neutrons), which opens the way to the fundamental possibility of obtaining both neutron matter in laboratory conditions, as well as hyper-heavy nuclei. Based on the works of Migdal, Tamm, and Hund, the possibility of existence of stable neutron matter (at Z>>175, N>>Z, A>10^3-10^5 with a size of 200-300 femtometers or more) at the micro level, and not only at the macro level, as is now considered in astrophysics. Neutron matter is considered as a potential cosmological candidate for dark matter, as well as the possibility of obtaining it in laboratory conditions. It is necessary to consider the possibility of formation of fragments of neutron matter as a dark matter (neutral, femto-, pico- and nano-dimensions, relict cooling makes it difficult to detect them by now) already in the initial birth of the Universe, which is the dominant process (as well as the primary black hole) and not the fusion of the initial minor number of protons. The observed part of the Universe is formed from the residual part of protons and subsequently decayed single neutrons and unstable fragments of neutron matter (with Z>175, N>> Z, but A<10^3-10^5). http://gamow.odessa.ua/?fbclid=IwAR3To79uzGk7YcbqkqWzVEpG5suy_DsZ-wx5GnFF8wczYXvraF43uhEuYLA
