Wavelength Standards in the Ultraviolet

September 1, 2002
Author(s)
Gillian Nave, Craig J. Sansonetti
We have made accurate wavelength measurements for lines of Pt 1 and II, Fe I, Ge I, and Kr II in the region 1800 to 3100 . New microlithography tools that are currently coming into production use are based on the ArF excimer laser which operates at a

Infrared Spectra of the Noble Gases

Author(s)
Craig J. Sansonetti, M M. Blackwell, Edward B. Saloman
The Atomic Spectroscopy Data Center of the National Institute of Standards and Technology (NIST) is currently compiling spectra and energy levels of the noble gases. A review of the literature has shown that there is no comprehensive experimental

Radiometry of Low-Pressure Hg-Ar Discharges

August 1, 2001
Author(s)
Craig J. Sansonetti, Joseph Reader
New fluorescent lamp designs employ Hg-Ar discharges under operating conditions that differ significantly from those found in conventional fluorescent tubes. We have studied the radiant output of Hg-Ar discharges over a wide range of Ar pressure, Hg vapor
