The acetylene was C188000100012 converted from barium carbonate enriched to 38.7% in C188000100013 14C . The resulting residues on tungsten backing was C188000100014 assumed to be carbon of the same isotopic constitution C188000100015 as the barium carbonate.No correction for possible C188000100016 target contamination was applied to the results.
