The project HILYS is aimed for obtaining the atomic parameters of highly-lying atomic states for atoms and their ions.
The main purpose of the project is calculation of the cross-sections and rates for electron impact excitation for levels up to n=10 for atoms and their ions with Z>26.
The diagnostic tools, which are available for obtaining the parameters of the emitting plasma from the observed line intensities in the spectra of astrophysical sources. More information on the projects can be found in the paper:
