    "abstract": "The low-lying n(=3,4,5)d $^2D_{5/2}$ states alkaline earth ions are of vital\nimportance in a number of different physical applications. The hyperfine\nstructure constants of these states are characterized by unusually strong\nelectron correlation effects. Relativistic coupled-cluster theory has been\nemployed to carry out {\\it ab initio} calculations of these constants. The role\nof the all order core-polarization effects was found to be decisive in\nobtaining good agreement of the results of our calculations with accurate\nmeasurements. The present work is an apt demonstration of the power of the\ncoupled-cluster method to cope with strongly interacting configurations.",
