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 for temperatures MeV in agreement with
recent experimental data for GDR in Pb and 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

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..
