Special Issue Information

Dear Colleagues,

We invite you to submit manuscripts for a Special issue of Atoms on “Atomic and Ionic Collisions: Laboratory and Astrophysical Relevance”. Many fields in physics and astronomy, depend on data for ionic, atomic and molecular collision processes. Nowadays, in the field of astrophysics modeling of these data is especially important and needed for simulations/calculations. Additionally, these processes are important for diagnostics, analysis and modeling of fusion plasma, laser produced plasma, lasers design and development and various plasmas in industry and technology. Among these amounts of data collection, there are collisional and radiative processes that even today are poorly represented. Therefore, there is an urgent need to collect these data, as well as to develop methods for improving the existing ones.

We would like to invite you to submit articles addressing collisional and radiative processes, so that these results will be used by other scientists and that the compilation of such data will be useful to data producers as well. This Special Issue aims to encourage further dialogue and knowledge transfer. Potential topics include, but are not limited to:

  • atomic data
  • molecular data
  • stellar spectra
  • laboratory plasma
  • fusion plasma
  • stars
  • atomic and molecular databases
  • Rydberg atoms
  • collisional atomic processes

To determine the photon emission or absorption probability for a diatomic system in the context of the semiclassical approximation it is necessary to calculate the characteristic canonical oscillatory integral which has one or more saddle points. Integrals like that appear in a whole range of physical problems, e.g., the atom–atom and atom–surface scattering and various optical phenomena. A uniform approximation of the integral, based on the stationary phase method is proposed, where the integral with several saddle points is replaced by a sum of integrals each having only one or at most two real saddle points and is easily soluble. In this way we formally reduce the codimension in canonical integrals of “elementary catastrophes” with codimensions greater than 1. The validity of the proposed method was tested on examples of integrals with three saddle points (“cusp” catastrophe) and four saddle points (“swallow-tail” catastrophe). Full article

Rare Earth Elements are important for stellar atmosphere analysis but the corresponding Stark broadening data are scarce. For Yb III and Lu IV theoretical as well as experimental data on Stark broadening parameters of spectral lines are absent in the literature. Using the modified semiempirical method of Dimitrijević and Konjević, we determined Stark widths for four Yb III and four Lu IV transitions, belonging to the erbium isoelectronic sequence. The obtained results are also used to discuss similarities between homologous transitions in the erbium isoelectronic sequence. We note as well that calculated widths will be implemented in the STARK-B database which is also a part of the Virtual Atomic and Molecular Data Center. Full article
