The mission of the NIST Atomic Spectroscopy Group is to measure, calculate, critically compile, and disseminate reference data on atomic properties and fundamental constants in support of basic research, commercial development, and national priorities. The group scientists perform measurements and analysis of atomic spectra from neutral and ionized (including highly-charged) atoms, collisional-radiative modeling, calculation of various atomic parameters etc.
