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…
