Karazin popup.description2 New experimental data of the angular distributions of the 11B+14C, 12C+7Li, 14N+7Li, 15N+12C, and 18O+6Li elastic and inelastic scattering as well as reactions simultaneously were measured for the transitions to the ground and excited states of he final nuclei at the energy Elab of the ions 11В, 12С, 14N, 15N and 18О equals to 45, 115, 80, 81, and 114 MeV respectively. These data were analyzed within the optical model and coupled-channel method to establish the dominant mechanism of the studied processes and to determine the nucleus-nucleus interaction potentials, in with such short-lived nuclei as 16N(T1/2=7.13 s). It was supposed that the cumulative effect of main individually weak channels, such as non-collective excitations of the target or transfer reactions can be especially important for the tunneling process at the complete fusion of the systems 20Ne + 58,60,61Ni, 90,92Zr, 118Sn and 208Pb, in particular they may enhance the fusion cross section at sub-burrier energies of the 20Ne ions, with obvious consequences for nucleosynthesis, superheavy element production, and reactions with halo nuclei or radioactive beams. The role of nuclear deformation in the formation of the energy distribution of the radiation E1-strength in the particle emission threshold region has been studied. Features of radiative effects, as defining physical and chemical influences necessary for increase of biological and catalytic activity of nanostructural samples modifying a factor in total from oxide of Zincum and dioxide of zirconium, and also getter selectivity of nanomaterials from natural zeolite, a magnetite and hematite to removal of the most dangerous radionuclides from fluid radioactive waste were for the first time established. It was made in experiments with use of a bremsstrahlung from powerful electron beams and a structure analysis of nanomaterials. Product Description popup.authors Гах Г. Дикий М. Луцай Н. Медвєдєва О.
