University of Wisconsin Radiocarbon Dates III

This report summarizes the radiocarbon dates obtained at the University of Wisconsin since November, 1965; the procedures followed and equipment used have been described previously (Wisconsin II). The dates reported have been calculated on the assumption of a half-life of 5568 yr for C 14 , 1950 as the reference year. Samples have normally been run at 3 atm pressure for a minimum of 15,000 counts. The standard deviation quoted includes only the 1 σ of the counting statistics of background, sample, and standard counts.
