Ranges of 40 keV ions in polycrystalline tungsten and gold.
Integral range profiles for various 40keV radioactive ions from (7)Be to (204)Tl were measured in tungsten and gold using sectioning techniques based on anodizing and stripping. Measured range distributions exhibited long tails extending into the metals. Median range values for a given ion were the same in tungsten as in gold, but were about 1.7 times greater than calculations of projected ranges based on the SRIM computer code.
