Abstract:
This work describes some computer programs that are available in compiled form for users of the SGI Power Challenge machine at Poznań Supercomputing and Networking Center. These programs give a possibility to solve very complex problems in the structure of free atoms using experimental data. The procedure of determination of the Slater integrals, spin-orbit parameters and also the parameters representing the effect of virtual excitations (many-body effects) is described. The program gives the propositions of the spectroscopic designations of energy levels. Moreover, the wavefunctions in intermediate coupling scheme in many-configurations approximation for the selected configuration system can be obtained.
