Research in atomic structure: A configuration interaction program with relativistic corrections
Description
Abstract The RIAS computer program implements the recent formulation for the evaluation of the matrix elements of the complete atomic Hamiltonian operator (S. Fraga et al., Phys. Rev. A 34 (1986) 23). The SL, J or F levels may be obtained by diagonalization of the interaction energy matrix constructed from appropriate SM_S LM_Lfunctions. The program allows for accurate determination of the energy levels of any neutral or ionized atomic system. Title of program: RIAS Catalogue Id: ABBB_v1_0 Nature of problem Determination of the energy levels of any neutral or ionized atomic system.
