The Molybdenum K-shell X-ray Emission Spectrum

Author(s)
Marcus H. Mendenhall, Lawrence T. Hudson, Csilla I. Szabo-Foster, Albert Henins, James P. Cline
Abstract We present newly measured spectra of the X-ray emission of a molybdenum metal anode subject to electron bombardment, using a very high dispersion

Contemporary x-ray wavelength metrology and traceability

Author(s)
Lawrence T. Hudson, James P. Cline, Albert Henins, Marcus H. Mendenhall, Csilla I. Szabo-Foster
We report recent advances in absolute x-ray wavelength metrology in the context of producing modern standard reference data. Primary standard x-ray wavelengths

High-precision measurement of the X-ray Cu K-alpha spectrum

Author(s)
Marcus H. Mendenhall, Albert Henins, Lawrence T. Hudson, Csilla I. Szabo-Foster, Donald A. Windover, James P. Cline
The structure of the x-ray emission lines of the Cu Kα complex has been remeasured on a newly commissioned instrument, in a manner directly traceable to the

The Lattice Spacing Variability of Intrinsic Float-Zone Silicon

Author(s)
Ernest G. Kessler Jr., Csilla I. Szabo-Foster, James P. Cline, Albert Henins, Lawrence T. Hudson, Marcus H. Mendenhall, Mark D. Vaudin
Precision lattice spacing comparison measurements at the National Institute of Standards and Technology (NIST) provide traceability of x-ray wavelength and
