Abstract: 
Applying atomic beam laser spectroscopy, hyperfine constants as well as level isotope shifts of the (6s2ns) S-2(1/2) levels (n = 7 - 12) and (6s2nd) 2D3/2, 5/2 levels (n = 6 - 10) have been measured in Tl-203 and Tl-205. Furthermore, some new hyperfine constants and level isotope shifts of the Tl P-2(1.2), P-2(3/2)-states are presented together with corrected results of earlier experiments. The hyperfine splittings have been compared with the predictions of the semiempirical theory. For the D-states a relatively poor agreement between these theoretical predictions and experimental results has been found. Using the experimental level isotope shifts and the delta[r2] value from muonic X-ray data, results of single-configuration Dirac-Fock calculations have been tested.
