- High-resolution laser spectroscopy measurements have been performed in the wavelength region around 4000 Å using a pulsed dye laser acting on a collimated atomic beam. Extra-cavity Fabry-Pérot filtering was used to achieve a narrow line-width of the laser light. Isotope shifts were measured in the 4216 Å and 4202 Å rubidium lines with the result ?s(87, 85)=124.3(4)MHz, and?s(87, 85) = 124.2(7)MHz, respectively, and in the 3988 Å ytterbium line with the resultds(176, 174)=-509(4)MHz, ?s(174, 172)=-530(4) MHz.

- High-resolution laser fluorescence spectroscopy, using a single-mode dye laser acting on a collimated atomic beam, has been performed to determine the hyperfine-structure (hfs) constants in six states of the 6p 5d configuration of135Ba and137Ba. Isotope shifts (IS) for eleven transitions between the 6s 5d and the 6p 5d configurations have also been measured. From an analysis of the energy levels, intermediate angular wavefunctions have been deduced. The wavefunctions are used to evaluate experimental hyperfine parameters from the experimental hfs constants. The parameters are, for the magnetic-dipole interaction compared with theoretical values, and for the electricquadrupole interaction used to estimate the nuclear quadrupole moments for the odd isotopes.

- Describes use of the quantum-beat method to study hyperfine structure in the 5 2 P 3/2 and 6 2 P 3/2 states of 23 Na. A pulsed dye laser, frequency-doubled into the UV region, was used to excite sodium atoms abruptly in a beam. The fluorescent light was recorded with a fast transient digitiser, interfaced to a micro-computer. Theoretical calculations using many-body perturbation theory were performed for the entire P sequence measured so far, taking polarisation and correlation effects into account separately. Very good agreement between experimental and theoretical values was obtained.
