The Dynamic Correlation Model (DCM) has been used to calculate nuclear ground-state wave functions of nuclei with one particle/hole in the closed shells. The strong mixing amplitudes between the valence particle/hole and the intrinsic vacuum states (valence hole coupled to core excitations) characterize the dynamic calculations of the hyperfine-structure splitting energy of the hydrogenlike ions which are in good agreement with measured values if the QED corrections are neglected. New experiments on the hyperfine-structure splitting energies of lithium-like ions could help in clarifying this still open point.
