A New Method for Analyzing 14C of Methane in Ancient Air Extracted from Glacial Ice

We present a new method developed for measuring radiocarbon of methane (14CH4) in ancient air samples extracted from glacial ice and dating 11,000–15,000 calendar years before present. The small size (∼20 μg CH4 carbon), low CH4 concentrations ([CH4], 400–800 parts per billion [ppb]), high carbon monoxide concentrations ([CO]), and low 14C activity of the samples created unusually high risks of contamination by extraneous carbon. Up to 2500 ppb CO in the air samples was quantitatively removed using the Sofnocat reagent. 14C procedural blanks were greatly reduced through the construction of a new CH4 conversion line utilizing platinized quartz wool for CH4 combustion and the use of an ultra-high-purity iron catalyst for graphitization. The amount and 14C activity of extraneous carbon added in the new CH4 conversion line were determined to be 0.23 ± 0.16 μg and 23.57 ± 16.22 pMC, respectively. The amount of modern (100 pMC) carbon added during the graphitization step has been reduced to 0.03 μg. The overall procedural blank for all stages of sample handling was 0.75 ± 0.38 pMC for ∼20-μg, 14C-free air samples with [CH4] of 500 ppb. Duration of the graphitization reactions for small (<25 μg C) samples was greatly reduced and reaction yields improved through more efficient water vapor trapping and the use of a new iron catalyst with higher surface area. 14C corrections for each step of sample handling have been determined. The resulting overall 14CH4 uncertainties for the ancient air samples are ∼1.0 pMC.

Decay of 134Cs

The gamma ray spectrum and the conversion line spectrum of 134Cs have been investigated using lithium-drifted detectors. The 563–569 and 796–802 keV doublets have been completely resolved for the first time. The energies in keV, relative intensities in percent per disintegration, and dominant multipolarities of the transitions observed are: 475.57(1.6%, E2); 563.06(8.6%, E2); 569.30(13.3 %, M1); 604.83(97.5%, E2); 796.02(87.0%, E2); 801.90(7.9%, E2); 1038.19(1%, M1 + E2); 1168.40(2%, E2); 1365.40(3.5%, E2); and 1580(0.03%, M1 or E2). The present results are consistent with the levels in 134Ba at 0(0+), 605(2+), 1168(2+), 1401(4+), 1580([Formula: see text]), 1643(3+), and 1970(4+) keV. There is no evidence for the previously reported levels at 923, 1062, 1374, 1770, and 1854 keV. The intensity of the beta-feeds to the levels at 1970, 1643, 1580, and 1401 keV respectively are 24.7%, 1.6%, 0.03%, and 73.7%, as computed from the intensity balance of levels in 134Ba. A modest attempt at comparison between the observed excited levels and theoretical predictions is made.

The Internal Conversion Electron Spectrum of 147Nd

The internal conversion electron spectrum following the β-decay of 147Nd has been studied using, an iron yoke and an iron free double focussing β-ray spectrometer at a momentum resolution of about 0.2%. A total of 66 transitions has been ascribed to this decay. On the basis of statistical analysis of sum relationships for the transition energies, combined with earlier reported coincidence results, a decay scheme involving 16 excited levels is suggested. The experimental data indicate a higher state at 763 keV. Its energy is close to the high state observed in other promethium nuclei.The multipolarity assignment for each transition was obtained by comparing the observed conversion line intensity ratios with the theoretical line intensity ratios of SLIV and BAND. From the multipolarity values obtained, the spins and parities of the excited levels in 147Pm are assigned and discussed in terms of recent nuclear models.
