EBIT Observation of Ar Dielectronic Recombination Lines Near the Unknown Faint X-Ray Feature Found in the Stacked Spectrum of Galaxy Clusters
Amy C. Gall, Adam R. Foster, Roshani Silwal +7
Motivated by possible atomic origins of the unidentified emission line detected at 3.55 keV to 3.57 keV in a stacked spectrum of galaxy clusters (Bulbul et al. 2014), an electron b…
Measuring the Variation in Nuclear Charge Radius of Xe Isotopes by EUV Spectroscopy of Highly-Charged Na-like Ions
R. Silwal, A. Lapierre, J. D. Gillaspy +8
The variation in mean-square nuclear charge radius of xenon isotopes was measured utilizing a new method based on extreme ultraviolet spectroscopy of highly charged Na-like ions. T…
Measurements and identifications of extreme ultraviolet spectra of highly-charged Sm and Er
Y. A. Podpaly, J. D. Gillaspy, J. Reader +1
We report spectroscopic measurements of highly charged samarium and erbium performed at the National Institute of Standards and Technology (NIST) Electron Beam Ion Trap (EBIT). The…
New x-ray measurements in Helium-like Atoms increase discrepancy between experiment and theoretical QED
Christopher T. Chantler, Andrew T. Payne, John D. Gillaspy +5
A recent 15 parts-per-million (ppm) experiment on muonic hydrogen found a major discrepancy with QED and independent nuclear size determinations. Here we find a significant discrep…
Anisotropic LMN dielectronic resonances from ratios of magnetic-dipole lines
Yu. Ralchenko, J. D. Gillaspy
Signatures of multi-keV LMN dielectronic resonances in highly-charged 3d^n ions of tungsten were detected in the intensity ratios of extreme-ultraviolet magnetic-dipole lines withi…
EUV magnetic-dipole lines from highly-charged high-Z ions with an open 3d shell
D. Osin, J. D. Gillaspy, J. Reader +1
The electron beam ion trap (EBIT) at the National Institute of Standards and Technology was used to produce highly-charged ions of hafnium, tantalum and gold with an open 3d shell.…
