Surfaces of polycrystalline U, Th, and single crystalline UO/sub 2/(111) were examined with He/sup +/, Ne/sup +/, and Ar/sup +/ at incident beam energies E/sub i/ less than or equal to 650 eV. A double-pass cylindrical mirror analyzer was used in a custom vacuum system intended primarily for UPS. The approach was to determine if the instrument could serve in a complementary ISS capacity and, if so, what the ion scattering conditions are for detecting surface oxygen and the actinides. Data are presented illustrating positive results. But severe limitations in resolution are evident, the energies do not correspond exactly to a simple binary-collision model, and with He/sup +/ the scattering intensities are quite low by comparison with an Au reference. 7 figures.
