The Topical Issue (TI), “Atomic spectra and oscillator strengths”, summarises the basic and primary atomic data needed in modelling a large variety of plasmas, covering radiative properties of atoms and atomic ions in different wavelength ranges going from X-ray to infrared (IR). These data find important applications in solar or stellar atmospheres and other astrophysical plasmas, and also in laboratory plasmas, such as fusion plasmas and laser-produced plasmas, among others.
The Topical Issue collects 19 papers, reflecting exchanges or collaborations between “producers” and “users” of atomic data. New developments of experimental and theoretical methods and the increasing completeness and quality of the data obtained are presented, often with the context of their potential applications. This implies precise experimental determination of spectral line wavelengths, level energies, lifetimes, oscillator strengths, hyperfine structures and Zeeman patterns. Theoretical investigations of atomic structures, with relativistic calculations of transition probabilities, collision cross-sections, as well as opacities, are also presented. The TI also includes examples of research review in astrophysics and the needs in atomic data. The community of atomic physicists carries on a constant effort to meet new requirements from astrophysics or other fields of physics, in particular by their works on heavy elements.
The Topical Issue follows the holding of the 14th International Colloquium on Atomic Spectra and Oscillator Strengths for Astrophysical and Laboratory Plasmas (ASOS14) in Paris from July 10 to 13, 2023, which aimed to perpetuate the purpose of the ASOS series by bringing together scientists from atomic physics, plasma physics and astrophysics for fruitful discussions.
