The program in atomic spectroscopy at NIST provides accurate reference data
on spectral lines and energy levels for a wide variety of important
applications. Our spectrometers, among the most powerful of their type in
the world, can record spectra from the extreme ultraviolet
(wavelength = 1 nm) to the infrared
(wavelength = 18 000 nm) and include a 10.7 m
normal-incidence spectrograph, a 10.7 m grazing incidence spectrograph,
a high resolution Fourier transform spectrometer, and a high accuracy
Fabry-Pérot laser wavemeter. The data centers compile wavelengths,
energy levels, and transition probabilities that support numerous
applications in industry and the scientific community.
The Atomic Spectroscopy Group at NIST has a long history of contributions to
optical science and metrology. Please read Joseph
Reader's report on the group's history for more information.

Younghee Kim, Edward Kim, George Noble, and Joseph Reader
Yong-Ki Kim, who joined NIST as a physicist in 1983, died in an automobile accident in September 2006. The Yong-Ki Kim Award for Excellence in Research was established by the family and friends of Yong-Ki to recognize junior scientists working in the areas of atomic structure, spectra, and collisions. The Award was presented at the annual meeting of the Division of Atomic, Molecular, and Optical Physics of the American Physical Society (DAMOP) in Calgary, Canada in May 2007. The Award Selection Committee consisted of Joseph Reader (Chair), Klaus Bartschat, Charlotte Fischer, Walter Johnson, and Kenneth Taylor. The Award, consisting of $1000 and a plaque, was given to George Noble (York University, Ontario, Canada) for his poster presentation at the DAMOP Meeting, “Isotope Shifts and Fine Structures of 6,7Li D Lines and Determination of Relative Nuclear Charge Radius.”
