NIST has published a comprehensive document on Fourier transform spectrometers and their applications in atomic spectroscopy research. The document includes recent publications by NIST researchers on the following topics:
1. Fe I Oscillator Strengths for the Gaia-ESO Survey: This study measured oscillator strengths for iron-56 atoms, which are important for understanding stellar spectra and chemical abundances in the Milky Way galaxy.
2. Extended Analysis of the Spectrum of Singly Ionized Chromium (Cr II): Researchers analyzed the detailed spectrum of chromium ions, providing precise wavelength measurements and energy level data for this element.
3. The Spectrum of Thorium from 250 nm to 5500 nm: This publication presents a comprehensive analysis of thorium’s spectral lines across a wide wavelength range, including Ritz wavelengths and optimized energy levels.
4. The Spectrum of Fe II: Researchers studied the spectrum of iron-56 ions, providing detailed line identifications and wavenumbers.
5. The Infrared Spectrum of Uranium Hollow Cathode Lamps: This study analyzed the infrared spectrum of uranium lamps, identifying spectral lines and providing wavenumbers and line identifications.
These publications demonstrate NIST’s ongoing research in atomic spectroscopy, using advanced Fourier transform spectrometers to measure precise wavelengths and energy levels of various elements. The data collected will be valuable for astronomical observations, plasma physics, and other fields that rely on accurate atomic spectra.
