University of Texas at Austin Radiocarbon Dates XIV
This list reports certain 14 C measurements completed by December 1979; other projects completed by this time will be reported later. Age calculations are based on 14 C half-life of 5568 yr and modern standard of 95% NBS oxalic acid, supplemented by tree rings of pre-industrial wood from a log cut in the 1850's (Tx-540; R, 1970, v 12, p 249). Deviations reported are based on counting statistics of sample, background and modern, and are ± 1σ, exce…

This list reports certain 14 C measurements completed by November 1978; other projects completed by this time will be reported later. Age calculations are based on 14 C half-life of 5568yr and modern standard of 95% NBS oxalic acid, supplemented by tree rings of pre-industrial wood from a log cut in the 1850's (Tx-540; R, 1970, v 12, p 249).

An Improved Procedure for Wet Oxidation of the 14 C Nbs Oxalic Acid Standard
An improved procedure for wet combustion of 14 C NBS oxalic acid standard has been devised which gives consistent high carbon yields and average δ 13 C values of —19.1‰. The principal cause of fractionation in earlier attempts to prepare CO 2 by the wet oxidation method was the inexact nature of the end-point. The new procedure employs a chocolate-brown end-point by adding 5ml more of the sulfuric acid-potassium permanganate solution after the in…

This list reports 14 C measurements completed between August 1973 and November 1975. Other projects completed in that period will be reported later. Age calculations are based on 14 C half-life of 5568 yr and modern standard of 95% NBS oxalic acid, supplemented by tree rings of pre-industrial wood from a log cut in the 1850's (Tx-540; R, 1970, v 12, p 249).

University of Texas At Austin Radiocarbon Dates IX
This laboratory is now a branch of the Texas Memorial Museum of the University of Texas at Austin. This list reports C 14 measurements made in projects completed between October 1969 and August 1971. A number of major projects are still in progress and are to be reported later. Age calculations are based on C 14 half-life of 5568 yr and modern standard of 95% of NBS oxalic acid. Deviations reported are based on counting statistics of sample, back…
University of Texas at Austin Radiocarbon Dates VII
This list reports C 14 measurements made in dating projects completed in the year ending December, 1968, and some measurements for projects still in progress. Age calculations are based on C 14 half-life of 5568 yr and a modern standard of 95% of NBS oxalic acid. Deviations reported are based on counting statistics of sample, background, and modern, and are ±1σ except that when sample count approaches either modern or background, 2σ limits are re…

University of Texas Radiocarbon Dates V
This list reports routine measurements made at this laboratory since the preparation of Texas IV. Samples numbered through Tx-309 were counted under the supervision of Pearson, who left the laboratory early in 1966. Valastro, Associate Director since August, 1966, is responsible for samples beginning with Tx-310. Laboratory administration and sample screening have been handled by Davis, M. A. Tamers, formerly Director, resigned in 1966
