“…The value of increasing the team size was shown by Wallmark et a1 without formality. This is discussed in a theoretical paper by Steck and Sundermann (1978). Workers in a big laboratory that embraces a wide range of knowledge have an advantage.…”

Surprisingly little attention has been paid to the question of what size is desirable for a whole laboratory as distinct from the groups that comprise it. A semi-quantitative analysis shows that while very small laboratories are handicapped by restricted common services there is also a heavy penalty paid by very large laboratories in the extended path over which information must flow between the working scientists and the decision makers. It is .not desirable, therefore, to expand research effort by allowing laboratories to grow indefinitely in size.

“…Each of the two hyperfine peaks is fit with an independent coupling Rabi frequency, but sidebands share the coupling Rabi frequency of the main peaks. The intermediate-state linewidth is fixed to the literature value: γ p = 2π × 3.03 MHz [27]. The excited-state linewidth γ c is fit to a common value for all peaks.…”

You will be contacted as soon as possible. We present direct measurements of the hyperfine splitting of Rydberg states in 87 Rb using electromagnetically induced transparency (EIT) spectroscopy in a room-temperature vapor cell. With this method, and in spite of Doppler broadening, linewidths of 3.7 MHz FWHM, i.e., significantly below the intermediate-state natural linewidth, are reached. This allows resolving hyperfine splittings for Rydberg s states with n = 20, . . . ,24. With this method we are able to determine Rydberg state hyperfine splittings with an accuracy of approximately 100 kHz. Ultimately, our method allows accuracies of order 5 kHz to be reached. Furthermore, we present a direct measurement of hyperfine-resolved Rydberg-state Stark shifts. These results will be of great value for future experiments relying on excellent knowledge of Rydberg-state energies and polarizabilities.

Mixing of ${0}^{+}$ and ${0}^{-}$ observed in the hyperfine and Zeeman structure of ultracold ${\mathrm{Rb}}_{2}$ molecules

We study the combination of the hyperfine and Zeeman structure in the spin-orbit coupled A b u u 1 3 Σ Π − + complex of Rb 87 2 . For this purpose, absorption spectroscopy at a magnetic field around B 1000= G is carried out. We drive optical dipole transitions from the lowest rotational state of an ultracold Feshbach molecule to various vibrational levels with 0 + symmetry of the A b − complex. In contrast to previous measurements with rotationally excited alkali-dimers, we do not observe equal spacings of the hyperfine levels. In addition, the spectra vary substantially for different vibrational quantum numbers, and exhibit large splittings of up to 160 MHz, unexpected for 0 + states. The level structure is explained to be a result of the repulsion between the states 0 + and 0 − of b u 3 Π , coupled via hyperfine and Zeeman interactions. In general, 0 − and 0 + have a spin-orbit induced energy spacing Δ, that is different for the individual vibrational states. From each measured spectrum we are able to extract Δ, which otherwise is not easily accessible in conventional spectroscopy schemes. We obtain values of Δ in the range of 100 ± GHz which can be described by coupled channel calculations if a spin-orbit coupling is introduced that is different for 0 − and 0 + of b u 3 Π .
