NIST Atomic Spectra Database

摘要: Accurate atomic data have great importance in astrophysics, plasma research, and other fields of physics. For more than 10 years, the Atomic Spectra Database (ASD) at National Institute Standards Technology has served as a convenient robust source critically evaluated on tens thousands spectral lines energy levels. The recent upgrade ASD represents significant new step development dynamic databases providing powerful tools for analysis manipulation. We present detailed description 3.0 emphasizing numerous advanced features options search presentation.
