Isovector Vibrations in Nuclear Matter at Finite Temperature

We consider the propagation and damping of isovector excitations in heated nuclear matter within the Landau Fermi-liquid theory. Results obtained for nuclear matter are applied to calculate the Giant Dipole Resonance (GDR) at finite temperature in heavy spherical nuclei within Steinwedel and Jensen model. The centroid energy of the GDR slightly decreases with increasing temperature and the width increases as $T^2$ for temperatures $T < 5$ MeV in agreement with recent experimental data for GDR in $^{208}$Pb and $^{120}$Sn. The validity of the method for other Fermi fluids is finally suggested.Comment: gzipped LaTeX file with text: 19 pages, 26 blocks; 3 gzipped *.ps files with figures: 50 block

Effects of irradiation of stainless steel and TiMoN coatings on stainless with lowenergy Alpha-particles, Krypton and Xenon ions

One of the directions for development of new structural materials for nuclear installations is deposition of protective coatings with high stability of physical and mechanical properties to ionizing irradiation on the existing structural materials. In particular, this applies to the nuclear reactors of generation IV, among which are considered as promising reactors with liquid metal and gas coolant..
