    Lifetime measurements in Tm I, Tm II, and Tm III by time-resolved laser spectroscopy (2003)
    Springer
    The European physical journal 23 (2003), S. 323-326

    ISSN: 1434-6079
    Keywords: PACS. 32.70.Cs Oscillator strengths, lifetimes, transition moments – 42.62.Fi Laser spectroscopy

    Notes: Abstract: Natural radiative lifetimes of eight levels in Tm I ( 4f 135d6p and 4f 125d6s 2 configurations), two levels in Tm II ( 4f 125d6s configuration) and three levels in Tm III (4f 125d configuration) have been measured by using time-resolved laser spectroscopy. Free thulium atoms, as well as singly and doubly ionized ions, were obtained in a laser-induced thulium plasma and the investigated states were selectively populated by a single-step excitation process with a tunable narrow-band laser pulse.

    Radiative lifetimes in Ce I and Ce II (2003)
    Springer
    The European physical journal 23 (2003), S. 233-236 
    Details
    ISSN: 1434-6079
    Keywords: PACS. 32.70.Cs Oscillator strengths, lifetimes, transition moments – 42.62.Fi Laser spectroscopy

    Topics: Physics
    Notes: Abstract: New radiative lifetime measurements based on time-resolved laser-induced fluorescence techniques are reported for 18 even-parity levels belonging to the 4f5d26p and 4f 25d 2 configurations of Ce I and 6 even-parity levels belonging to the 5d26s, 4f5d6p, and 4f6s6p configurations of Ce II. Free neutral and singly ionized cerium atoms were produced by laser ablation. The Ce I and Ce II levels range in energy from 26 545 to 29 102 cm-1, and 42 573 to 48 152 cm-1, respectively.
