| Abstract: | Radiative lifetimes of 7d, 8d 1 D 2 excited states of Hg I are measured using pulsed two-photon excitation from the ground [Xe]5d 106s 2 1 S 0 mercury state, detecting the decay of the laser-induced fluorescence. The results are compared with theoretical values, obtained by means of a Hartree-Fock single configuration method, taking into account electron configuration interaction. The radiative lifetime value dependence on the effective principal quantum number for the nd 1 D 2 series is analyzed and compared with the quantum defect dependence.
