Аннотация

The spectrum of excitation of Rydberg states of thallium atoms has been investigated using a collimated atomic beam in a two-step isotope selective laser scheme 62P1/2 → 62D3/2 → Tl** in the presence of an electric field with a strength of up to 1.5 kV/cm near the level 16F5/2. The optical transitions 6D3/2 → 18D3/2 and 6D3/2 → 16G7/2, which were induced by an external electric field and dipole-forbidden, have been studied experimentally. The values for the scalar polarizabilities (in units сm–1/(kV/сm)2) α0(16F5/2) = 3.71 ± 0.3, α0(18D3/2) = 11.70 ± 0.25, and α0(16G7/2) = 44.1 ± 0.9, which are compared with the calculated one, have been obtained. The new values of energy parameters for the states 18D3/2 and 16G7/2 have been determined.
