A VUV light source for enhanced production of metastable krypton and xenon beams
Patrick R. Stollenwerk, Kevin G. Bailey, Daniel Koch +4
We demonstrate excitation of metastable krypton and xenon beams using a vacuum ultraviolet lamp and directly compare the performance of this method to metastable excitation based o…
High Resolution Spectroscopy of Neutral Yb Atoms in a Solid Ne Matrix
R. Lambo, C. -Y. Xu, S. T. Pratt +11
We present an experimental and theoretical study of the absorption and emission spectra of Yb atoms in a solid Ne matrix at a resolution of 0.025 nm. Five absorption bands were ide…
Rapid processing of 85Kr/Kr ratios using Atom Trap Trace Analysis
J. C. Zappala, K. Bailey, P. Mueller +2
We report a methodology for measuring 85Kr/Kr isotopic abundances using Atom Trap Trace Analysis (ATTA) that increases sample measurement throughput by over an order of magnitude t…
Setting a Limit on Anthropogenic Sources of Atmospheric 81Kr through Atom Trap Trace Analysis
J. C. Zappala, K. Bailey, W. Jiang +4
We place a 2.5% limit on the anthropogenic contribution to the modern abundance of 81Kr/Kr in the atmosphere at the 90% confidence level. Due to its simple production and transport…
Using 81Kr and Noble Gases to Characterize and Date Groundwater and Brines in the Baltic Artesian Basin on the One-Million-Year Timescale
Christoph Gerber, Rein Vaikmäe, Werner Aeschbach +12
Analyses for Kr and noble gases on groundwater from the deepest aquifer system of the Baltic Artesian Basin (BAB) were performed to determine groundwater ages and uncover th…
Measurement of the Hyperfine Quenching Rate of the Clock Transition in Yb
C. -Y. Xu, J. Singh, J. C. Zappala +8
We report the first experimental determination of the hyperfine quenching rate of the transition in Yb with nuclear spin $…
