dc.description.abstractThe low-lying n(=3,4,5)d 2D5/2 states of alkaline-earth-metal ions are of vital importance in a number of different physical applications. The hyperfine structure constants of these states are characterized by unusually strong electron correlation effects. Relativistic coupled-cluster theory has been employed to carry out ab initio calculations of these constants. The role of the all-order core-polarization effects was found to be decisive in obtaining good agreement of our calculated magnetic dipole hyperfine structure constants with accurate measurements. The present work is an apt demonstration of the power of the coupled-cluster method to cope with strongly interacting configurations.en
