    Reactivity of small transition metal clusters (1993)

    Notes: Abstract A new experiment for measuring the reactivity of neutral metal clusters is presented. A low pressure reaction cell is used to measure the sticking ofO 2 andD 2 gas on small transition metal clusters ofCu, Fe, Co andNi. The experiment yields absolute values for the sticking, at a controlled number of cluster/gas collisions, facilitating comparison with theoretical calculations and other experiments. The most striking result of these preliminary measurements is the difference between oxygen sticking onCo N and onCu N , with the sticking onCu N showing a clear correlation to the electronic shell model, while the sticking onCo N only exhibits a sharp increase with size, reaching sticking probability=1.0 forN〉25.

    Notes: Abstract Laser and radiofrequency spectroscopy have been employed in order to measure the hyperfine structure in93Nb. We report the hyperfine structure splittings of 17 metastable states in the 4d 45s, 4d 35s 2 and 4d 5 configurations and of 14 states in the higher lying configurations 4d 45p and 4d 35s5p.

    Parameterization of the hyperfine structure of metastable states in103Rh (1989)
    Springer
    The European physical journal 14 (1989), S. 139-142 
    Details
    ISSN: 1434-6079
    Keywords: 35.10.F ; 31.30.G
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The experimental data on the hyperfine structure of metastable even parity states in103Rh have been analysed by means of an effective-operator formalism. The effective radial parameters of the magnetic dipole interaction are determined, using wave functions in intermediate coupling. The comparison with relativistic calculations gives an estimate of the effects due to configuration interaction.

    Notes: Abstract The hyperfine structure (hfs) of181Ta has been investigated using laser radio-frequency double resonance and high resolution laser spectroscopy on collimated atomic beams. The magnetic dipole and electric quadrupole hyperfine structure coupling constants of the 5d 4 6 s 6D 3/2, 5/2, 7/2, 9/2 metastable states have been determined using radio-frequency spectroscopy. In the 5d 4 6s 6 D 1/2 metastable state and the excited 5d 3 6s 6p 4 D 3/2,6 D 5/2, 9/2 as well as the unidentified 28 182.6 cm−1 and 30 021.2 cm−1 states, hfs constants have been obtained from high resolution laser spectroscopy. A radio-frequency converter has been developed in order to reach the frequency region 2.7–10 GHz.
