University of Pennsylvania Radiocarbon Dates VIII

Abstract

This date list includes those series of archaeologic samples completed in this laboratory during 1963 and 1964. The b.p. ages are calculated from a.d. 1950, and are based upon a half-life value of 5568 yr. Errors quoted do not include the half-life error. All samples have been pretreated with 3N HCl, and some, where noted, have received an additional 2% NaOH pretreatment for the removal of possible humic acid contaminants.
