Depth Concentration

Results of the depth profiling of a laser mirror are reported and discussed. The sample was bombarded with 40Ar+, 32O2+ and 16O- in order to establish optimum conditions. It was found that the bombardement by means of 16O- results in the best depth concentration profile

Depth Concentration

Atomic oxygen states adsorbed at silver surface have been studied by angle-resolved XPS. It has been shown that all states have different structure of adsorbed layers. This allowed us to conclude that ARXPS followed by depth concentration profile restoration is useful technique for analysis of the adsorbate location with respect to upper substrate layers.

Total Body

The heart is generally considered a radioresistant organ, and has received relatively little study after total-body irradiation with doses below the acutely lethal range. Some late damage in the irradiated heart has been described at the light microscopic level. However, since the dimensions of many important structures of the blood vessel wall are submicroscopic, investigators have turned to the electron microscope for adequate visualization of histopathological changes. Our studies are designed to evaluate ultrastructural changes in the mouse heart, particularly in the capillaries and muscle fibers, for 18 months after total-body exposure, and to compare the effects of 240 rad fission neutrons and 788 rad 60Co γ-rays.Three animals from each irradiated group and three control mice were sacrificed by ether inhalation at 4 days, and at 1, 3, 6, 12, and 18 months after irradiation. The thorax was opened and the heart was fixed briefly in situwith Karnofsky's fixative.
