The nuclear-nuclear interaction potentials for the 16O+92Zr and 16O+116Sn systems were calculated within the framework of the modified Thomas-Fermi method with Skyrm forces, using the nucleon densities obtained in the same approximation. The experimental values of the ratio for nuclei 197,195Au, 196,198,199,200Hg, 201Tl, 207,209Bi, 208,210,211,212Po, 213At were analyzed within the framework of a statistical approach. A model for describing the characteristics of fission fragments is proposed, within which the mass and charge distributions of fission fragments are well described, as well as the average kinetic energy of fission fragments. An expression was obtained to describe the dependence of the average total kinetic energy of the fission fragments on the excitation energy of the fissioning system in a simple model that takes into account statistical and quantum properties. The results of the first measured weighted average yields of (γ,p) reactions at the limiting bremsstrahlung energy of 20 MeV. The developed method of research of current-current characteristics of diamonds without metallization of their contact surfaces is described. The Fe-Al-C, Fe-Co-Ti-C and Fe-Ni-C systems were studied in detail. The problems of developing designs of technical means of controlling the parameters of charged particles of low and ultra-low energy are studied. Analytical expressions for the amplitudes and observed characteristics of elastic scattering of protons by 40Ca nuclei in the second Born approximation were obtained. A modification of the TSE method is proposed for the description and prediction of photon power functions with excitation of low-energy and high-energy states. The effect of electron beam irradiation at an energy of 1 MeV on the optical and morphological properties of reduced graphene oxide was studied. Product Description popup.authors Ivanov Yuri V.
