The radius of the core can be chosen as a constant, but the ratio (4) is most often used.



Expression (4) is calculated in fermi, equal to a femtometer or 10>—15 m. Now, when the kinetic energy and the Coulomb barrier have been determined, as well as the particle has already passed through it, having spent a certain part of its energy and entered the reaction, having overcome a distance of 10>—15 from the nucleus – the radius of the Coulomb barrier, it is possible to determine the value of the new kinetic energy (5), indicating some note that the initial kinetic energy indicated here is determined after the passage of a particle through the atomic structure of a particular material, which includes the target nucleus, however, such an algorithm most often refers to the atomic, molecular scale and spending on these phenomena are not so significant, most often appearing in the form of some kind of scattering on the present material.



Further, after these expressions, first of all it is necessary to determine the type of nuclear reaction – calculate the energy yield of the nuclear reaction (6).



A simpler calculation of the present expression can be provided due to the fact that the mass of each of the components of a nuclear reaction is calculated in atomic units of mass and after performing elementary arithmetic operations is multiplied by the square of the speed of light, also represented in MeV, which for 1 a. u. m. is equal to 931.5 MeV. As a result, a positive or negative output of the nuclear reaction is obtained, from which it is possible to determine the exa- or endo-energy of the nuclear reaction.

It was stated above that a particle can expend a certain amount of energy, which will be spent not only on Coulomb, but also on other barriers. In order to determine their approximate sum, the concept of the energy threshold of nuclear reactions (7) is used.



In this case, all the necessary indicators are known and give the general state of the reaction. Further, it is desirable to present the general energy equation of such a nuclear reaction (8), after which it is possible to proceed to the determination of the kinetic energy of the results of a nuclear reaction.



In order to determine the kinetic energy of the nuclear reaction products, it should be noted that each of the particles receives an initial energy additional balance equal to the sum of the reaction output and the second kinetic energy of the directed particle after the Coulomb barrier, in an inversely proportional to its own mass ratio (9—10).
