Scientific justification

The purpose of the International Colloquia on Atomic Spectra and Oscillator Strengths for Astrophysical and Laboratory Plasmas is to bring together producers and users of atomic (and molecular) data.
Atomic physicists who study the structure of atoms and their radiative and collisional properties are invited to describe the latest progress of their discipline, while astrophysicists and laboratory plasma physicists are invited to review their present research interests and the context in which atomic data are needed.

The scientific program consists of four days of invited talks, contributed talks and poster presentations. Some of the areas of interest for discussion include:

  • atomic lifetime and oscillator strength determination
  • hyperfine structure and isotope shifts
  • theoretical modeling and computational approaches
  • laboratory techniques
  • high resolution spectroscopy
  • trapped ions
  • tests of fundamental constants
  • highly charged ions
  • collisional processes
  • atomic databases and related topics
  • astrophysical and laboratory plasmas: atomic data needs
  • spectroscopic diagnostics of fusion plasmas
  • topics in astrophysics including elemental abundance determination
  • atomic spectra from HED plasmas and polarization

ASOS-12 is the twelfth colloquium in a series started in Lund, Sweden, in 1983, and subsequently held in Toledo, Ohio, USA (1986), Amsterdam, Netherlands (1989), Gaithersburg, Maryland, USA (1992), Meudon, France (1995), Victoria, Canada (1998), Belfast, UK (2001), Madison, Wisconsin, USA (2004), Lund, Sweden (2007), Berkeley, California, USA (2010), and Mons, Belgium (2013).
