    Notizen: Abstract: Lifetimes of some 3p5nd (n = 4, 5, 6, 7) levels of neutral argon have been measured by high frequency deflection technique with a delayed coincidence single photon counting arrangement. The measurements have been performed under conditions where pressure dependent effects are negligible. Lifetimes of some of the levels have been measured for the first time. The results have been compared with other experimental and theoretical values.

    Theoretical transition probabilities and lifetimes in nickel-like Se , Y and Sn ions (2003)
    Springer
    The European physical journal 23 (2003), S. 5-13 
    Details
    ISSN: 1434-6079

    Thema: Physik
    Notizen: Abstract: The 17 levels of the 3 d 10 , 3 d 9 4 s and 3 d 9 4 p configurations, and the electric-dipole transitions among these levels are calculated for the three nickel-like ions Se6+, Y11+ and Sn22+ by using large-scale multiconfiguration Dirac-Fock wavefunctions. From these computations, the excitation energies and transition probabilities as well as the lifetimes of 3 d 9 4 p levels are derived, including all dominant effects of relativity, correlation and of the rearrangement of the electron density within the same framework. Comparison is made with the scarce number of experimental data and previous semi-empirical computations.

    Radiative lifetimes of 7d, 8d 1D2 excited states of Hg I (2001)

    Notizen: 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.
