Abstract
The dynamic correlation model was used to calculate nuclear ground-state wave functions of Tl-203, Tl-205, and Tl-207. The ground states of these isotopes are characterized by strong mixing amplitudes of the valence 3s(1/2)(-1) hole with the intrinsic vacuum states (valence hole coupled to core excitations). Nuclear magnetic moments, radii, and the 1 s hyperfine-structure splitting energy for the hydrogenlike ions were calculated. Experimental magnetic moments and radii of the nuclear ground states are well reproduced. The hyperfine-structure splitting of the hydrogenlike Tl isotopes have not been measured so far, hence, the obtained values are only compared with predictions of other, theoretical calculations. The difference in the 1s hyperfine-structure splitting between Tl-203(80+) and Tl-205(80+) its found to be 0.026 eV, which corresponds to a 3.1 nm shift in the transiton wavelength.
