英文摘要Using the relativistic coupled-cluster method, we calculate the static dipole polarizabilities of the 6p, 7s, 7p, 8s, 8p, and 6d states and the dynamic dipole polarizabilities of the 6p and 7s states of the thallium atom. The trivalent thallium atom is computationally treated as a monovalent system, together with all linear and nonlinear terms of single- and double-cluster operators included in the correlation calculations. We observe that the dominating contributions to the static scalar polarizabilities of the 7s(1/2), 7p(1/2), 8p(1/2), and 8p(3/2) states are from one or two specific transitions. The matrix elements of these specific transitions can be determined by combining the experimental values of relevant static scalar polarizabilities. A number of magic wavelengths for the 6p(1/2)-7s and 6p(3/2)-7s transitions in the range of 488-1300 nm and the longest tune-out wavelength of the ground state are determined. These magic wavelengths and tune-out wavelength may be useful for further thallium experiments. Experimental measurements of the magic wavelengths near 1245 nm would give estimates of the 7s(1/2)-7p(1/2) and 7s(1/2)-7p(3/2) transition matrix elements and their ratio. Furthermore, lifetimes of many excited states, as well as the Stark-induced scalar and vector dipole polarizabilities for the 6p(1/2)-7p(1/2) transition, are also evaluated and compared with available theoretical and experimental values.
