Abstract
The level of purity of a target foil is very important in low cross se ction nuclear reaction experiments. Carbon foils prepared by two diffe rent techniques were analyzed for their content of light impurities su ch as nitrogen, oxygen, and sodium. These data indicate that the techn ique used to manufacture a foil is the largest source of contamination . Foils prepared by vacuum evaporation showed sizable levels of light impurities, whereas foils prepared by chemical vapor deposition were s ubstantially purer.
