Applied Physics and Mathematics Annotation << Back INTERACTION OF NUCLEI IN LOW-ENERGY NUCLEAR REACTIONS L.B. BOLDYREVA The condition for performing the low-energy nuclear reaction is possibility of fusion of nuclei with sufficiently low energy. An obstacle to this process is the Coulomb repulsion of nuclei existing due to the same sign of their electric charges. The aim of this work is to show that compensation of Coulomb interaction for subsequent implementation of nuclear fusion (for example, between coaxial protons in nickel-hydrogen reactor) is a result of interaction of virtual photons created by protons of these nuclei. The concept of virtual photons was developed by Nobel Prize winner R. Feynman in 1949; one of the main properties of virtual photons is their ability to interact with each other by dipole electric interaction. Besides the compensation of Coulomb interaction of nuclei, dipole electric interaction of virtual photons can explain the emergence of «nuclear molecules». The concept of virtual photons can explain also the following properties of the Low-Energy Nuclear Reactions: «mass defect»; the radiation of electromagnetic oscillation and objects similar to ball lightning; the generation of spin supercurrent. Keywords: Low-Energy Nuclear Reactions; virtual photon; «mass defect»; Coulomb interaction; ball lightning; spin supercurrent. DOI: 10.25791/pfim.04.2025.1337 Pp. 03-16.
