“…As the hyperfine splittings for both lines are known with high precision [5], the FSR of the FP-interferometer could be very accurately determined as will be shown in Section 4. One of the first measurements of isotope shifts using laser techniques was performed on the Yb 5556 A line (6s6p 3p~_6s 21S0 ) by Broadhurst et al [6]. In our previous paper we also studied this line with the present technique [1].…”

High-resolution laser spectroscopy measurements have been performed in the wavelength region around 4000~ using a pulsed dye laser acting on a collimated atomic beam. Extra-cavity Fabry-P6rot filtering was used to achieve a narrow line-width of the laser light. Isotope shifts were measured in the 4216h and 4202~ rubidium lines with the result A o-(87, 85) = 124.3(4) MHz, and A o-(87, 85) = 124.2(7) MHz, respectively, and in the 3988~ ytterbium line with the result Ao-(176, 174)=-509(4)MHz, Aa(174, 172)= -530(4) MHz.

“…vestigations. We can nevertheless recall the fact that such techniques have proved to be very useful when studying isotopic shifts, or elements that cannot be studied as readily as alkali atoms: for instance, Broadhurst et al (1974) obtained results for Yb that improve on previous determinations by an order of magnitude.…”

“…Determination of the absorption coefficient as a function of probe laser detuning allows us to extract both the Doppler and pressure widths. We use previously measured values for the separation of hyperfine and isotope components in our fits [21][22][23][28][29][30]. We assume the same broadening and shift for all hyperfine components.…”

Results of an investigation of collisional de-excitation of the metastable 6s6p 3 P 0 state in atomic ytterbium by helium and neon buffer gases are reported. We find upper limits for the quenching cross sections to be σ He < × − 13 10 22 cm 2 and σ Ne < × − 8 10 22 cm 2. The small cross sections may allow an ytterbium parity nonconservation experiment to be performed in a vapor cell. We have also measured the pressure broadening and shift of the 6s6p 3 P 0 → 6s7s 3 S 1 and 6s 2 1 S 0 → 6s6p 3 P 1 transitions by helium and neon.
