The primary state of damage in platinum and tungsten caused by ions of varying mass and energy was investigated using the field ion microscope (FIM). The damage could be classified into three morphological types: (a) depleted zones (DZs); (b) voids; (c) dislocation loops. Platinum specimens of 99.999% purity were irradiated in situ at 60 K with 20 keV Kr/sup +/ ions to a dose of (3 to 5) x 10/sup 12/ ion cm/sup -2/ and examined by the pulse field-evaporation technique at 60 K. The experimental conditions were created such that each depleted zone was created by a single incident ion. All three morphological types were observed.
