Abstract
We report the relativistic coupled cluster study of the hyperfine structure and effect of the nuclear magnetization distribution (Bohr-Weisskopf effect) in the , and states of several Tl isotopes. It is shown that the Gaussian basis set can be used in such electronic structure calculations and provide a good accuracy. For the ground electronic state of the neutral Tl atom achieved uncertainty for the hyperfine structure constant is smaller than 1\%. A strong Bohr-Weisskopf correction (about 16\%) was found for the state which can be of interest for the nuclear structure theory. Basing on the theoretical treatment as well as the available experimental data nuclear magnetic moments of short lived Tl and Tl isotopes were also predicted.
