The low-spin structure of the 206 Tl nucleus has been investigated with the FIPPS prompt γray spectrometer of ILL making use of the 205 Tl(n;γ) 206 Tl reaction and the γcoincidence technique. A large number of excitations up to the neutron binding energy (at 6.5 MeV) in 206 Tl were observed. Preliminary results of the data analysis provided the information on the decay scheme of the capture state in 206 Tl and on the multipolarities of a number of rays. The comparison of the experimental data with shell-model calculations will help describing the proton-hole and neutron-hole couplings near the doubly magic core 208Pb, benchmarking single-particle levels and two-body matrix elements of the residual interaction in this important region of the nuclear chart.
