PHYSICAL SYSTEM OF SIMPLE SUBSTANCES AND THEIR ISOTOPES AND MATHEMATICAL MODEL OF PROPERTIES IDENTIFICATION
Physical system of simple substances and their isotopes is formed on the basis of known quantitative values of physical parameters: the atomic number, atomic mass, the number of neutrons in the nucleus, nuclear pattern of decomposition, half-life period, spin, parity, neutron energy in allocation. A mathematical model of a physical system allows to express each physical parameter as a function in the form of an analytical expression of the remaining parameters and to calculate their values, even if it is unknown. They are given the results of model calculations of unknown values for half-life isotopes of oxygen, argon and vanadium, and neutron energy in allocation of isotopes of hydrogen, helium, lithium and boron.
